For the class "Embedded system design," I along with my three classmates developed a semi-autonomous switchboard to reduce power consumption in hostel washrooms. The washroom was divided into two areas - Common area and Toilets. The Common area lights were controlled automatic via entry sensors (consisting two ultrasonic sensors) and Toilets were controlled via timer switches. The modular switchboard was also accompanied by a simple UI and a manual for customizing the board as per need.

My primary contribution was to design a Printed Circuit Board (PCB) and integrate individual codes prepared by my teammates to formulate an overall control loop. We chose Arduino as the main controller which was programmed in C++. I designed the PCB in Autodesk EAGLE software and generated gerber files for manufacturing. 

We installed a prototype for a demonstration on the Open House Day of our university.
