Internet of Things requires communication to devices that are either actuators or sensors. Each actuator and sensor has an identity. Each actuator and sensor may be either directly connected to the world wide web or indirectly connected via a type of gateway.
Communication to these devices needs to be reliable. Therefore each device may implement their most suitable communication protocol.

Distributed coordination protocol for event data exchange in IoT monitoring a...Maynooth University
Publish-subscribe architecture is one of the dominating architectural styles in designing the Internet of things (IoT) monitoring applications. Establishment of a brokerless publish-subscribe system leads to exchanging a high number of control messages including advertise, subscribe and update messages. Additionally, the in-efficiency in forwarding publish messages in a resource-constrained IoT environment results in network congestion, communication delay, and energy loss.
The recent approaches in brokerless publish-subscribe systems for IoT domain introduced new communication protocols, maintaining routing tables of IoT nodes, and clustering the network. However, the efficiency in exchanging control messages does not receive much attention. In this paper, we propose an enhanced communication protocol to establish a brokerless publish-subscribe IoT system. The protocol is based on beaconing for packet dissemination. We applied a new structure that provides metadata in the packet header that facilitates the receivers regarding their next possible actions. The simulation results demonstrate that the proposed method reduces the network traffic by 28% on average and decreases the energy consumption of nodes up to 33%. The results also reveal that the number of publish messages is reduced by 10% in comparison to the baseline method.

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.
Introduction to Arduino Hardware and ProgrammingEmmanuel Obot
Introduction to Arduino Hardware and Programming:
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It's intended for anyone making interactive projects.
Teachers and students use it to build low cost scientific instruments, to prove chemistry and physics principles, or to get started with programming and robotics. Designers and architects build interactive prototypes, musicians and artists use it for installations and to experiment with new musical instruments. Makers, of course, use it to build many of the projects exhibited at the Maker Faire. Arduino is a key tool to learn new things. Anyone - children, hobbyists, artists, programmers can use it to build an interactive device.
Arduino is an open-source project that created microcontroller-based kits for building digital devices and interactive objects that can sense and control physical devices.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

Honest Reviews of Tim Han LMA Course Program.pptxtimhan337
Personal development courses are widely available today, with each one promising life-changing outcomes. Tim Han’s Life Mastery Achievers (LMA) Course has drawn a lot of interest. In addition to offering my frank assessment of Success Insider’s LMA Course, this piece examines the course’s effects via a variety of Tim Han LMA course reviews and Success Insider comments.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

IOT beginnners
1. IOT
writing IoT firmware, software, and OS’s for
IoT devices.
There’s 3 distinct parts to any legitimate
IoT product
Wanted to master it
1. Software
2. Hardware
3. Network
2. First, buy an arduino
• Some cool sensors/lights/led screens or
whatever floats your boat.
• It’s not about building cool stuff, it’s about
learning (both are possible at the same time!).
• If familiar move on to TI sensor tag
3. Network part
• Most important part.
• The more efficient your data transfers are
from device to device to server to device and
everything in between, the smaller and faster
your device can be.
4. Concepts to master:
• IoT is the convergence of like everything in tech. To
master IoT, you basically need to master computers. Is
that possible?
• Operating Systems/Firmware
• Printed Circuit Board Design
• Cloud/IoT Network Architecture
• C/C++
• Pretty much everything full-stack related. Backend
programming, mobile programming, machine
learning/AI, big data/analysis, cloud computing.
9. What is an Arduino?
Features
• 14 Digital I/O pins
• 6 Analogue inputs
• 6 PWM pins
• USB serial
• 16MHz Clock speed
• 32KB Flash memory
• 2KB SRAM
• 1KB EEPROM
10. Getting Started
• Check out: http://arduino.cc/en/Guide/HomePage
1. Download & install the Arduino environment (IDE)
(if needed)
2. Connect the board to your computer via the USB cable
3. If needed, install the drivers (if needed)
4. Launch the Arduino IDE
5. Select your board
6. Select your serial port
7. Open the blink example
8. Upload the program
11. The Arduino IDE
The main features you need to know about are:
• Code area: This is where you will type all your
code
• Info panel: This will show any errors during
compiling or uploading code to your Arduino
• Verify: This allows you to compile your code to
code the Arduino understands. Any mistakes you
have made in the syntax of your code will be
show in the info panel
• Upload: This does the same as verify but will
then send your code to your Arduino if the code
is verified successfully
• Serial Monitor: This will open a window that
allows you to send text to and from an Arduino.
We will use this feature in later lectures.
13. Structure of an Arduino “sketch”
//pins can be thought of as global variables
void setup()
{
// put your setup code here, to run once:
}
void loop() // equivalent to while(1) { }
{
// put your main code here, to run
repeatedly:
}
14. • setup : It is called only when the Arduino is
powered on or reset. It is used to initialize
variables and pin modes
• loop : The loop functions runs continuously till
the device is powered off. The main logic of
the code goes here. Similar to while (1) for
micro-controller programming.
Minimum code
15. • A pin on arduino can be set as input or output
by using pinMode function.
• pinMode(13, OUTPUT); // sets pin 13 as
output pin
• pinMode(13, INPUT); // sets pin 13 as input
pin
PinMode
16. • digitalWrite(13, LOW); // Makes the output
voltage on pin 13 , 0V
• digitalWrite(13, HIGH); // Makes the output
voltage on pin 13 , 5V
• int buttonState = digitalRead(2); // reads the
value of pin 2 in buttonState
Reading/writing digital values
17. • What is analog ?
• It is continuous range of voltage values (not
just 0 or 5V)
• Why convert to digital ?
• Because our microcontroller only understands
digital.
Analog to Digital Conversion
20. • The Arduino Uno board contains 6 pins for
ADC
• 10-bit analog to digital converter
• This means that it will map input voltages
between 0 and 5 volts into integer values
between 0 and 1023
ADC in Arduino
21. • analogRead(A0); // used to read the analog
value from the pin A0
• analogWrite(2,128);//Used to create 50% duty
cycle
Reading/Writing Analog Values
25. Serial Communication
• Compiling turns your program into
binary data (ones and zeros)
• Uploading sends the bits through
USB cable to the Arduino
• The two LEDs near the USB
connector blink when data is
transmitted
• RX blinks when the Arduino is
receiving data
• TX blinks when the Arduino is
transmitting data
27. // These constants won't change. They're used to give names to the pins used:
const int analogInPin = A0; // Analog input pin that the potentiometer is attached to
const int analogOutPin = 9; // Analog output pin that the LED is attached to
int sensorValue = 0; // value read from the pot
int outputValue = 0; // value output to the PWM (analog out)
void setup() {
Serial.begin(9600); // initialize serial communications at 9600 bps:
}
void loop() {
sensorValue = analogRead(analogInPin); // read the analog in value:
outputValue = map(sensorValue, 0, 1023, 0, 255); // map it to the range of the analog out:
analogWrite(analogOutPin, outputValue); // change the analog out value:
Serial.print("sensor = " ); // print the results to the serial monitor:
Serial.print(sensorValue);
Serial.print("t output = ");
Serial.println(outputValue);
// delay(2000); // wait 2 seconds before the next loop for the analog-to-digital converter to settle after the last reading:
}
ADC Example
28. PIR Sensor Interfacing
• used for motion detection
• detect the Infrared waves emitting from a particular
object
• human or animal body emits heat energy in a form of
infrared radiation
• made of pyro-electric materials
• when this material is exposed to heat then, it
generates energy
29. PIR Sensor Interfacing
• consists a specially designed cover named
Fresnel lens, which focuses the infrared
signals onto the pyroelectric sensor.
31. PIR Sensor Interfacing
int sensor=7; //The output of PIR sensor connected to pin 7
int sensor_value; //variable to hold read sensor value
void setup()
{
pinMode(sensor,INPUT); // configuring pin 7 as Input
Serial.begin(9600); // To show output value of sensor in serial monitor
}
void loop()
{
sensor_value=digitalRead(sensor); // Reading sensor value from pin 7
Serial.println(sensor_value); // Printing output to serial monitor
delay(500);
}
35. Cloud Platforms for Internet of Things
(IoT)
• Google Cloud’s IoT Platform
• Pricing on Google Cloud is done on a per-
minute basis, which is cheaper than other
platforms.
37. Cloud Platforms for Internet of Things
(IoT)
• AWS IoT Platform
• Amazon made it much easier for developers to
collect data from sensors and Internet-
connected devices. They help you collect and
send data to the cloud and analyze that
information to provide the ability to manage
devices.
38. IoT protocols
• Divided in terms of the role they play within
the network.
• Communications (Wi-Fi, Bluetooth),
• Data transmission (MQTT, CoAP, XMPP),
• Security (DTLS), and
• Device management as well as telemetry
39. MQTT
• Message Queuing Telemetry Transport
• Lightweight messaging protocol that was
developed by IBM and first released in 1999.
• It uses the pub/sub pattern and translates
messages between devices, servers, and
applications.
40. CoAP
• Which easily translates to HTTP for integration with the existing
Web
• Specialized web transfer protocol for use with constrained nodes
and constrained networks in the Internet of Things.
• CoAP is designed to enable simple, constrained devices to join
the IoT even through constrained networks with low bandwidth
and low availability. The Constrained Application Protocol (CoAP) is
a specialized web transfer protocol for use with constrained nodes
and constrained (e.g., low-power, lossy) networks.
• The nodes often have 8-bit microcontrollers with small amounts of
ROM and RAM, while constrained networks such as IPv6 over Low-
Power Wireless Personal Area Networks (6LoWPANs) often have
high packet error rates and a typical throughput of 10s of kbit/s.
• The protocol is designed for machine- to-machine (M2M)
applications such as smart energy and building automation.
