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 one delivers the output voltage. I used an ...

Here is the diagram of my Arduino infrared close proximity sensor. As you can see, the core part of my experimental setup is an Arduino UNO, but other compatible microcontrollers can also be employed.

One such innovative project is ... on how to construct an infrared camera using an Arduino UNO, an infrared sensor AMG8833, and an 8×8 RGB LED display from SunFounder. Thermal cameras are ...

It contains three LEDs, red, green, and blue. Each one indicates the status of a different function. The Arduino uses Ken Shirrif’s IR Remote library to handle the infrared remote control functions.
