All SD Card works on 3V interface so if your microcontroller is working on 5V you will need to convert these signals.
Micro SD Memory Card Interface for 3.3V MCURaghav Shetty
This is a wonderful little SD card interface module. It is easily interfaced as a peripheral to your module. Through programming, you can read and write to the SD card.All SD Card works on 3V interface so if your microcontroller is working on 3V you can use this board readily. The interface board provided is for microcontrollers running at 3V.
The regulated power supply accepts unregulated inputs from 9V to 15V AC or DC and gives regulated output of 3.3V, 5V and 12V suitable for projects which needs precise voltage to work. The input can come from step down transformer. Since board has Diode Bridge input polarity does not matter. All outputs are brought to screw terminal. There is also an unregulated output voltage to drive high current loads like relays and motors.
With this board you can develop and prototype with any of Microchip's 40 pin PIC microcontrollers. The RS232 driver on board allows easy connection with PC or other embedded hardware. The bridge rectifier allow this board to be powered with both AC and DC power supply adapters
8 Channel Bi Directional Logic Level ConverterRaghav Shetty
Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.This 8-bit non inverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V. This allows for universal low-voltage bidirectional translation between any of the 1.2-V, 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V voltage nodes. VCCA should not exceed VCCB.
One of the basic interfacing requirements for the hobbyists or electronics enthusiasts is I/P (keypad) and O/P (LCD display) for prototype applications. This shield uses minimum number I/O’s that is 4 bits for LCD data and 2 control signal lines for the same. A single analog pin (Pin A0) is multiplexed to read 5 input key switches (Navigation keys). Each key has been pulled up to a different voltage level, so a different voltage will be generated every time a user selects a key. This voltage could be read by the analog pin A0 on the board. Hence saves the no of I/O pins. The backlight of the LCD could be controlled by setting PWM (Pin D10) by adding a few lines of code.
The L298 Driver is a high voltage, high current dual ful bridge driver designed to accept standard TTL logic levels and drive inductive loads such relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the input signals. The emitters of the lower transistors of each bridge are connected together the corresponding external terminal can be used for the connection of an external sensing resistor.
The Joystick Shield easily stacks on top of your ATmega 328 and turns it into a simple robotic and gaming controller. Six momentary push buttons (4+2), a two-axis thumb joystick and optional remote transmission adapter for Xbee and Bluetooth allows your ATmega 328 to control from remote location. ATmega 328 digital pins D3-D8 are connected to momentary push buttons, when pressed they will pull the pin HIGH. Voltage accross analog pin 0 varies proportionally for the vertical movement of the joystick, like wise horizontal movement can be tracked at analog pin 1.Xbee Dout is connected to D0(Rx) and Din is connected to D1(Tx) of ATmega 328 sheild.
This is a force sensitive resistor with a round, 0.5" diameter, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1M. This FSR can sense applied force anywhere in the range of 100g-10kg.

Flex Sensor 4.2" ROHS Compliant Description: A simple flex sensor 4.2" in length. As the sensor is flexed, the resistance across the sensor increases. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend). Connector is0.1" spaced and bread board friendly. Note: Please refrain from flexing or straining this sensor at the base. The usable range of the sensor can be flexed without a problem, but care should be taken to minimize flexing outside of the usable range. For best results, securely mount the base and bottom portion and only allow the actual flex sensor to flex.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert

POWER MODES
Power down mode
SIM900A is set power down mode by “AT+CPOWD=0”
There are two methods for the module to enter into low current consumption status
Minimum Functionality Mode
Minimum functionality mode reduces the functionality of the module to a minimum and thus
minimizes the current consumption to the lowest level.
If SIM900A has been set to minimum functionality by “AT+CFUN=0”
If SIM900A has been set to full functionality by “AT+CFUN=1”
If SIM900A is set “AT+CFUN=4” to disable both the above functionality.
Sleep mode
We can control SIM900A module to enter or exit the SLEEP mode in customer
applications through DTR signal. When DTR is in high level and there is no on air and hardware
interrupt (such as GPIO interrupt or data on serial port), SIM900A will enter SLEEP mode
automatically. In this mode, SIM900A can still receive paging or SMS from network but the
serial port is not accessible.
Wake up SIM900A from sleep mode
Enable DTR pin to wake up SIM900A. If DTR pin is pulled down to a low level
This signal will wake up SIM900A from power saving mode. The serial port will be
active after DTR changed to low level for about 50ms.
Receiving a voice or data call from network to wake up SIM900A.
Receiving a SMS from network to wake up SIM900A.
