A Video Overview of

Arduino and the AVR Microcontroller

Prof. Harry Porter

Portland State University

These videos introduce and describe the AVR microprocessor and the Arduino single board computers. We discuss the instruction set architecture of the AVR, the software programming and downloading process, and conclude with an example program. We go over the code, show how it is compiled and loaded into the Flash memory on the board, and demonstrate the resulting system using a button and knob to control an LED and servo motor.
