Note: A compact analogue reflectance sensor such as the CNY70 was not used in the Arduino Uno experiments described. Instead, a homemade sensor was assembled using a single infrared LED (IR333C) and a ...

The connections are very simple as the IR Receiver sensor only has three pins, Vs, GND, and Data. Connect Vs and GND pin of IR Receiver to 3.3V GND pin of Arduino and Data pin to Digital pin 2 of ...

The part list consists of one Arduino, two resistors, and one IR emitter. That’s right, an emitter. When an LED (IR or otherwise) is reverse biased it can act as a light sensor.

For first part, upload IR_decoder.ino code to Arduino. Connect the circuit as shown in Fig. 1. MP3 Vire (21-key) remote was used during testing. Compile and upload the code to Arduino. Now, point the ...
