Project: Electronics Bash - #18- Timers

To this point, we've been handling all of the timing and timekeeping in our Arduino programs by hand. If the-next-thing needs to happen at a specific time, or a specific number of milliseconds from now, we've been tracking all that with variables and millis() statements and so on. What if there wa a way for that all to be taken care of in the background, automatically? And what if it was something we'd been doing all along without our knowing it?

Topics Include:

  • Timers in the ATmega328
  • Timer Interrupts and Configuration
  • Timers and built-in Functions (AnalogWrite, Tone, Millis, Delay, Servo)
  • Using timers to build new code
