AVR Microcontroller. LED flasher using timers. Timers interrupts. Timer CTC Mode.

Hello everyone!

Timers is an important concept in the field of electronics. Every electronic component works on a time base. This time base helps to keep all the work synchronized. All the microcontrollers work at some predefined clock frequency, they all have a provision to set up timers. AVR boasts of having a timer which is very accurate, precise and reliable. It offers loads of features in it, thus making it a vast topic. The best part is that the timer is totally independent of the CPU. Thus, it runs parallel to the CPU and there is no CPU’s intervention, which makes the timer quite accurate. In this video we explain the basic concepts of AVR Timers. We are writing simple program in C code to control LED flasher, using timers.
