Today I decided to implement the pomodoro technique with my arduino.
It turns on an orange led (I didn't have a red one) from 10 to 10 seconds, just to remember me that I'm in a busy time, while a tic tac is reproduced by the buzzer.
After the first 25 minutes -- suggestion by Francesco Cirillo, the author of the pomodoro technique -- an alarm is activated. Then, a green led is turned on for 5 minutes -- so, I can rest a bit -- and the loop continues.
It's working pretty well, =)
The source code is available at my github -> https://github.com/cathoderay/pomoino/blob/master/pomoino.pde
Till the next experiment =)
