AVR

AVR is a family of 8-bit microcontrollers developed by Atmel (now part of Microchip Technology) that uses a modified Harvard architecture with separate memory spaces for program and data. These microcontrollers are widely used in embedded systems and maker projects due to their ease of programming, built-in peripherals like timers and ADCs, and extensive development tool support. AVR microcontrollers are particularly popular in educational settings and hobbyist applications, with the Arduino platform being built around AVR chips like the ATmega328P.
