Makeblock Me IR Line Finder
The Me - Line Finder module is designed for the line following robotics. It has two sensors on the
module and each sensor contains two parts - an IR emitting LED and an IR sensitive phototransistor. It
can output digital signal to Arduino so the robot can reliably follow a black line on a white background,
or vice versa.
Features
• 5VDC power supply
• 4 Pin RJ10 interface and 2.54mm breakout pins
• Compatible with Me - Base Shield
• Detecting range: 1~2cm
LED indicator
• PWR (Red LED) - Power indicator
• SENSOR1 (Blue LED) - Sensor1 status indicator. Lighten shows black line detected by Sensor1.
• SENSOR2 (Blue LED) - Sensor2 status indicator. Lighten shows black line detected by Sensor2.
Usage
As the Blue tag illustrated, the Me - Line Finder can be connected to the port 3, 4, 5 or 6 of the Me -
Base Shield by a telephone wire.
