#Atmega #arduino #adventcalendar #FOSS #linux Welcome to my AVR advent calendar. Here you can learn in 24 days how to program AVR 8-bit microcontrollers and use the most important interfaces of them. For programming microcontrollers we will need some basic bit operations. I will show you how they work in this video.
