WebApr 5, 2024 · A timer is a piece of hardware built in the Arduino controller and depending on the model, it could have different number of timers. For example, the Arduino UNO has 3 timers, Timer0, Timer1 and Timer2. Timer is like a clock, and can be used to measure time events. The timer can be programmed by some special registers (cpu memory) so is like ...
