How To Use And Program ATmega Microcontrollers From Scratch Without Arduino

Last Updated on January 14, 2026 by Swagatam

ATmega microcontrollers, they are coming from the AVR family which Atmel developed long back, and later this Atmel company was taken by Microchip. So now officially Microchip owns it but still people say Atmel AVR only. These MCUs became very popular slowly because they are easy to understand, quite affordable, stable in long run and […]
