LED Indicator: The LED blinks in response to the sensor's detection of an object. The blinking behavior is controlled by the Arduino based on the sensor's output. Circuit Connections: IR Sensor VCC ...

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.

🔦 Infrared-based light controller using an Arduino Nano, photoresistor, and IR LED. Automatically turns an LED strip on/off based on ambient light. Includes schematic, code, and 3D-printable case.

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 Arduino Sketch is a chimera of two code examples for IR LEDs and the gesture sensor — courtesy of the always estimable Ken Shirriff, and SparkFun respectively.
