Auduino - Lo-Fi Arduino Synthesizer

In this instructable I will show you how I made the Auduino synthesizer. It is meant to be listened on headphones but if you want to listen on speaker you will have to use an amplifier which I will show in other instructable. The circuit is relatively simple. For me the hardest part was to burn the bootloader on a blank atmega328 and uploading the program.”
