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.

The Arduino Uno IR Receiver Module detects and receives infrared (IR) signals transmitted by IR remote controls or other IR transmitters. It typically includes a photodiode and a circuit to decode the ...

In my case I have used only 3 x 330Ω resistors, 3 leds and a TSOP4838 IR receiver module. You must check the datasheet before use the IR module to see which pins connect to the power supply and which ...

IR REMOTE CONTROL CAR WITH ARDUINO When the car is powered on, the L293D motor shield and the IR receiver module are activated through the Arduino UNO board. The IR receiver then captures the IR ...
