The ST Line Follower Sensor has a digital output (line or no-line) and includes on-board LEDs which provide instant feedback about the sensor status, without requiring PC connection for debugging.
The ST Line Follower Sensor is very easy to use. Just connect it with a standard 3-pin cable (usually called servo extension cable). It can be wired to a breadboard or just connected to the headers of the ST EDU board ST-00101 or most other robotic boards (like BOE, Shield BOE, etc.).
