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.

All of the Arduino code you need to get up and running is also provided. The main limitation when using this configuration, is that the remote control needs to be very close to the IR emitter in ...

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 ...

The IR receiver module is represented here by IRRX, powered from a 5-Vdc supply. An infrared emitter (IRED) is available for changing the hardware as an IR encoder.
