This lab assignment involves using a serial peripheral interface (SPI) to connect an analog-to-digital converter (ADC) to a microcontroller in order to measure voltage and temperature readings. Students will configure the SPI to interface the microcontroller as a master to the ADC as a slave. Then they will use a potential divider circuit connected to an ADC channel to display voltage readings on an LCD. Finally, they will connect a temperature sensor to another ADC channel and display real-time temperature readings on the LCD. Teaching assistants will verify the students' ability to demonstrate these SPI setups and measurements.

Controlled power is a prerequisite of various sectors, including industries. The
implementation of microcontroller based firing angle control, using ATmega 32 MCU and
associated hardware circuitry is discussed here. Main emphasis is given on improved
performance of converter so as to achieve reliable and consistent power control. The power
control scheme uses commonly available components like ATmega-32 controller,
transistorized conditioning circuit, rectifier module, for firing angle control. The objective is
to achieve a reliable, affordable and accurate power control mechanism for the use of
industrial and household consumer applications, with superior performance.
Automated Air Cooled Three Level Inverter system using ArduinoIJEEE
The output voltage of a three level inverter is stepped voltage in which the output voltage have three possible values. Such systems can be used to interface renewable energy sources with the grid. Temperature has significant effect on performance of power MOSFETs. Typically, the MOSFETs used as power switches in such applications are a significant source of heat, and the heat energy dissipated by these components must be carefully controlled if operating temperatures are to be maintained. So for the system to work efficiently cooling of MOSFETs is required. This paper proposed an automated air cooled 3 level H-bridge inverter. The system consists of MOSFETs, LM 35 temperature sensor, Optocouplers for isolation. Arduino is used to control the on-off operation of fan. When temperature rises above certain level fan turns on to cool the MOSFETs.
This paper describes the testing of boost rectification required in the back-to-
back converter used in doubly fed induction generator (DFIG) based wind energy
conversion systems (WECS). In this work testing is carried out on the single phase rectifier
section of back-to-back converter. Detail design of components of back to back converter is
explained. The hardware module of this back-to-back converter is fabricated in the
departmental laboratory. dSPACE and Microcontroller 8051 is used for implementing the
control. Results show that required boosting is satisfactorily obtained.

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.

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.
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.
