Controlling an LED with Arduino Using an IR Sensor An Infrared (IR) sensor is a commonly used device for proximity detection and object sensing. When combined with an Arduino and an LED, it can create ...

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 ...

int IRSensor = 8; // connect ir sensor to arduino pin 2 int LED = 11; // connect Led to arduino pin 13 ...

It is built around Arduino Leonardo (Board1), IR sensor TSOP1738(IRRX1) and remote control. - Advertisement - Connections are simple. Connect GND pin of the sensor to GND pin, Vcc pin to 5V pin, and O ...
