The hardware consists of a simple open hardware design for the Arduino board with an Atmel AVR processor and on-board input/output support. The software consists of a standard programming language compiler and the boot loader that runs on the board.\n\n== Arduino Board Models ==\n\n{| class=\"wikitable\"\n!
