Arduino remote-controlled LEDs

Welcome to a new Arduino project. In this tutorial, you will learn how to control LEDs remotely with Arduino using an infrared remote control. We will also cover the materials used, the wiring diagram, and the code needed to turn LEDs on and off remotely.

Materials

Below you can see the different materials used in this remote LED project with Arduino together with a brief description of each one. If you want to build it yourself, you can click the images to go to a website where you can buy the materials.

Arduino Uno board: it is the brain of the project and controls every part of it through the code you will find below.

A board with interconnected holes (pins) that we use to make all the project connections.

Remote control: a device that sends different infrared signals depending on which button is pressed.

LED: A light-emitting component based on a p-n junction.

Jumper wires: these wires have male or female pin connectors that let us connect the different elements mentioned above.

Arduino wiring diagram for the remote-controlled LEDs

One of the most important parts of assembling the LEDs and the receiver used to control them with the remote is connecting the different elements correctly. To avoid assembly mistakes or incorrect connections, here is the wiring diagram used in this project. With this wiring, you can use the code at the end of the post without making any modifications.

Arduino code for the remote-controlled LEDs

Below you can find the code developed specifically for this project. The pins used in the code are the same ones shown in the wiring diagram above.

If you want a more detailed explanation of the different parts of the code used to program these LEDs and how they work with an infrared remote control, I recommend watching the video linked above.
