A digital or binary decoder is a digital combinational logic circuit which can convert one form of digital code into another form.
BCD to 7-segment display decoder is a special decoder which can convert binary coded decimals into another form which can be easily displayed through a 7-segment display.
In Binary Coded Decimal (BCD) encoding scheme each of the decimal numbers(0-9) is represented by its equivalent binary pattern(which is generally of 4-bits).
Whereas, Seven segment display is an electronic device which consists of seven Light Emitting Diodes (LEDs) arranged in a some definite pattern (common cathode or common anode type), which is used to display Hexadecimal numerals(in this case decimal numbers, as input is BCD i.e., 0-9).

The number of persons who are paralyzed and therefore dependent on others due to loss of self-mobility is growing with the population. The development of the wheelchair for paralyzed users is surprisingly recent starting with the conventional manually powered wheelchairs and advancing to electrical wheelchairs. Conventional wheelchair use tends to focus exclusively on manual use which use which assumes users still able to use their hands which excludes those unable to do so. Diseases or accidents injuring the nervous system also frequently because people lose their ability to move their voluntary muscle. Because voluntary muscle is the main actuator enabling people to move their body, paralysis may cause a person not move their locomotor organ such as arm, leg and others. Paralysis may be local, global, or follow specific patterns. Most paralysis are constant, however there are other forms such as periodic paralysis (caused by genetic diseases), caused by various other factors.
Scientist Stephen W. Hawking is perhaps the most well-known victim of major paralysis – Hawking was diagnosed with incurable Amyotrophic Lateral Sclerosis (ALS) in 1962, thereafter using a wheelchair to move. Many of those suffering close to or complete paralysis usually however still can control their eye movement which inspired us to develop an eye-controlled electric wheelchair.

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

A Strategic Approach: GenAI in EducationPeter 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.

1. EMBEDDED SYSTEMS TUTORIAL6- INTERFACING 7
SEGMENT DISPLAY WITH AVR
Hii… friends its our next AVR tutorial this time we are going to discuss about interfacing of 7 segment
display with a AVR. You must have seen 7 segment display in you house hold inverters, in a zerox
machine or even on your microwave oven. So in this tutorial , We will discuss about 7 segment display ,
its types and its interfacing with AVR along with source code so have a look…
INTROUCTION
A seven segment display is the most basic electronic display device that can display digits from 0-9.
They find wide application in devices that display numeric information like digital clocks, radio, microwave
ovens, electronic meters etc. The most common configuration has an array of eight LEDs arranged in a
special pattern to display these digits. They are laid out as a squared-off figure ‘8’. Every LED is assigned
a name from 'a' to 'g' and 'dp'and is identified by its name. Seven LEDs 'a' to 'g' are used to display the
numerals while eighth LED 'dp' is used to display the dot/decimal.
PACKAGE AND TYPES
A seven segment is generally available in ten pin package. While eight pins correspond to the eight
LEDs, the remaining two pins (at middle) are common and internally shorted. These segments come in
two configurations, namely, Common cathode (CC) and Common anode (CA). In CC configuration, the
negative terminals of all LEDs are connected to the common pins. The common is connected to ground
and a particular LED glows when its corresponding pin is given high. In CA arrangement, the common pin
is given a high logic and the LED pins are given low to display a number .
2. HOW IT WORKS
Now let us suppose a digit is to be displayed on the 7 segment. Suppose the digit is 1 in
such case LEDS corresponding b and c should glow, so we can say foe each and every
digit a specific set of LEDs has to glow . the LEDs to be golw with corresponding digits
Are as shown.
3. INTERFACING WITH AVR MICROCONTROLLER
Here is step wise process for inTERfacing a 7 segment display with AVR
microcontroller( ATMEGA 16)
SETP 1
CICUIT CONNECTION
Here we are using a common anode 7 segment display.
Connect your 7 segment display with the atmega 16 as per the connections shown in
the diagram below
4. STEP 2
SOURCE CODE
Create the new project in AVR STUDIO4 and compile the code written below-
/*
A simple program for interfacing common anode seven segment display with AVR
microcontroller
9. In this program first we have created a function to display digits named
seven_segment_display, then we have passed two argument first to display numbers
and other to display decimal point if we want. We are going to connect our 7 segment at
PORT C, so we will make it output port and after that the corresponding pins connected
to 7 segment pins are set to high or low according to number to be displayed. This
program will display the no from 0 t0 9 and as it reaches to 9 , it will be reset to 0. You
can change numbering sequence or display only odd or odd number or whatever you
want just by some small changes in the source code according to your task.
Now burn the microcontroller with the hex file generated and power up your
circuit , you will see numbers displaying from 0 to 9.
So we have learnt the basics of 7 segment display interfacing, we can more 7 seven
segment display with a AVR but for that we will need multiplexing technique, we will
discuss multiplexing in upcoming tutorials but before that we have to discuss about
TIMER in AVR so in next tutorial we will discuss about TIMER s
