Today I finished the interface module for my raspberry pi based retro car radio. The module interfaces the buttons, the variable resistor and a RGB-led using an ATMega 328p running an arduino firmware.
This is my day 30 project for 30daysOfCreativity but I think I will need to extend my 30 days a bit so I can finish this project :-)
Day 26 of 30DaysOfCreativity - prototyping the controls
Day 24 of 30DaysOfCreativity - a breadboard arduino
Day 19 of 30DaysOfCreativity - RGB led for the Raspberry PI based Radio
RadioPI - debugging
