A simple walkie-talkie circuit running off an Arduino Nano. Utilizes a BJT to amplify the microphone voltage and transmits the radio signal through a nRF24L01 series Transceiver.
A simulated blinking LED circuit using an astable multivibrator a.k.a "flip-flop" as a square wave generator. It also includes PCB layout of the project.
