Making a PCB cover that lights up with my name in RGB lights that can be controlled through an app on the phone.

Design a transmitter and receiver using nrf24l01 & atmega328p To send data from one point to another over a distance of up to 1.5 km.

To use the AtMega328p ic without Arduino Uno board I made this PCB and combined two boards into one PCB to reduce production cost.

A speed sensor that measures the speed of objects and displays it on a 7 segment display I used firmware & hardware component.

An electrical circuit that turns a light on and off by clapping.
