I went through the forum and read that you can't use digital pins 0 & 1 as inputs or outputs if your using serial communication i.e. serial begin. Now I'm trying to use it as button inputs but it is not working, I'm not using serial print and my wiring is the same as in the arduino button example of here: http://arduino.cc/en/Tutorial/Button
If I move my button inputs to digital pins 2 & 3 it is working like a charm but on 0 & 1 it just won't budge. With the project I'm currently working on the only available pins are digital pins 0 & 1, the rest are all used and I want to move the buttons located at 2 & 3 to 0 & 1 so that I can use the PWM output at pin 3 and use pin 2 to switch something on and off.
When I connect my buttons inputs to pins 0 & 1 and I press one of the buttons then the TX led lights up, I don't know if this might be a clue. Any input would be greatly appreciated. Thank you very much.
