'''AVR''' is a family of [[RISC]] [[microcontroller]]s from [[Atmel]]. Unlike the [[PIC]], the AVR [[instruction set]] is compatible across models. The AVR was designed for efficient execution of [[compiler|compiled]] [[C programming language|C]] code. Thus some instructions, such as add immediate, are strangely missing (you have to subtract immediate the complement instead) and others, such as compare with carry, are included.

Like the [[PIC]], it has a dedicated hobbyist following (exemplified by the [http://www.avrfreaks.net AVRFreaks] forum), largely due to the existence of cheap/free development tools.
