I’m extremely excited because I was able to port my LED Clock setup from Arduino Mega2560 to ATMega644P on breadboard.
Sound Works.
LED Display Works.
All buttons and Clock functionality works.
Only thing that doesn’t work is temperature sensor. It requires 3.3V AREF and I don’t have 3.3V power supply right now 🙁 Not sure why it doesn’t work with 5 Volts. Without reference voltage I’m getting crazy readings from the IC. But it’s a minor issue, I’m sure I’ll find a way around it.
