Prescaler, why we need? It also can be used for counter to skip certain number of microcontroller clock ticks. AVR microcontroller allows prescaling or skipping number of 8, 64, , You could see if counter count up to 15, then you can able to blink LED at every second. Timer in compare mode or to say CTC mode, instead of counting until overflow occurs.

The timer compares its count to the value that previously stored in register. When count matches that value then timer can either set a flag or trigger an interrupt same as happen in case of overflow. Example Tutorial: In this example, we are going to use timer This is bit timer and to keep simple and short we are using no-prescaler. Refer datasheet page number Outer loop inside while loop is used to count TCNT1 register upto counts. I recommend you to try this example by your own and play little bit around with the code by modifying some parameters to get inside detail of how timer works with internal clock.

I hope you will find this tutorial educational and entertaining.
