Has anyone toyed with making an HIIT timer with a Netduino? Basically it is 2 timers back to back and you set the value for timer 1 and timer 2. (Timer one can be anywhere from 10 seconds to 5 minutes and 2 can be anywhere from 5 seconds to 5 minutes).
Think I am gonna try to do this, gonna probably have to do the display using a Max7219 and (6) 7 segment numbers, and then I'll need 7 inputs (increase set time, decrease set time, adjust timer 1, adjust timer 2, start, stop, and reset) and 2 outputs (buzzer and led to signal).
Just curious if anyone else has toyed with this idea and if they came across any issues to look out for.
