Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...

This project demonstrates how to control 4 servo motors using an *Arduino Uno board. The servos are connected to the Arduino board and will move in a sweeping motion (from 0° to 90° and back to 0°).

Uses line-following and obstacle sensors to navigate a pre-defined course. Controls two DC motors (differential drive) for movement and turning. Drives a servo motor to raise/lower a marker for ...
