    This project is based on the save power concept, in bathrooms, we turn on lights and forget to turn them off which leads to power wastage .to tackle this problem we need to set the delay to lights to means after 7 -10 min of turning on the light it will automatically turn off, need to design a circuit to solve this problem

    We call on all electronics makers to develop a working prototype of a launch speed indicator we have with us. The launch speed indicator has to sense a moving shuttle passing nearby it with two hall sensors. The LSI design, programming and testing have to be done. The LSI would need to log the speed data which shows up on a LED display after each possible also the log the time date of the should have two buttons for powering on and off of the LSI and selections.

    ...power supply and I need a PCB created to control it. I would need it to have a buck boost circuit that could do 0vdc-60vdc @5amps as well have a current limiting feature for testing equipment, etc. & perhaps digipots to control the output voltage and current limiting digitally through the menu. I also will be using a TFT LCD to display a menu & to show voltages & current draw, so using an STM32 to drive & control all the logic would be preferable. Im not sure which batteries would be best to use in this so achieve the desired power outputs that I want so perhaps you may have some suggestions for batteries but for whichever batteries it would need a BMS and all protections as well with a USB C recharging circuit for recharging it & finally a power switch...

    I'm currently working as a software Engineer at Wai Technologies. These days I'm working on a project called raaghu react which is an open-source React-based front-end design system leveraging micro-frontend capabilities that helps in building efficient, reliable, and scalable front-end applications. This experience has led me to get exposure to Javascript, Typescript, Bootstrap, ReactJS, Webpack5 and Module Federation. Apart from this, my hunger to learn, consistency in efforts, and sincerity in the task at hand, set me apart from others. Also, I possess the ability to go the extra mile to get things done.

The primary circuit is connected to a source of hot water (fernwärme/district heating) that maintains a temperature between 60 and 120 degrees, and a permanent pump that can not be controlled or regulated. The secondary circuit is also connected to a constant-speed pump and the goal is to maintain a temperature of about 40 degrees. I have implemented a basic control logic using switch cases and if-else statements, but I am having trouble getting the system to accurately regulate the temperature of the secondary circuit.
