The 1802 processor dates from the earliest days of hobby computing. The Olduino is an adapter board that lets the 1802 use modern peripherals and components meant for an Arduino. Carbot is an Olduino project that adapts a battery powered car to race around a small arena keeping a fixed distance from the walls. It includes infra-red and ultrasonic sensors, an analog-to-digital converter, a motor driver, a battery boost regulator, and an XBee wireless bridge all built onto an arduino-style shield.
