This sensor can be used to help a robotic car follow a black line. 1). Adjusting. Place the sensor such that there is 12mm between reflective photosensor and white (or light) colored surface. 2).

Connect Grove - Infrared Reflective Sensor to any port of Grove-Base Shield via the Grove cable, we use D2 in this demo. Step 3. Place this sensor 12mm above the white(or other bright color) paper.

Arduino Uno/Nano (Board1) For uploading code: 1: Analogue reflectance sensor module or (IR and phototransistor pair) for example, CNY70 or homemade: 1: 330Ω, ¼W resistor: Current limiting: 1: 10KΩ, ¼W ...
