How IR Remotes and Receivers WorkĪ typical infrared communication system requires an IR transmitter and an IR receiver. It can’t transmit through walls or other materials like WiFi or Bluetooth. The only difference between IR light and visible light is the frequency and wavelength. Infrared radiation lies outside the range of visible light, so humans can’t see it:īecause IR is a type of light, IR communication requires a direct line of sight from the receiver to the transmitter. Infrared radiation is a form of light similar to the light we see all around us. Now let’s get into the details… What is Infrared? It includes all of the parts, wiring diagrams, code, and step-by-step instructions for 58 different robotics and internet of things projects that are super fun to build! The 3-in-1 Smart Car and IOT Learning Kit from SunFounder has everything you need to learn how to master the Arduino.
