As it is clear, both the decoding and switching tasks are done just by one 8-pins ATTiny85 microcontroller. So let’s get started and build this puppy!įigure 1 shows the schematic diagram of the device. The device works stable and reacts well to the transmitted IR signals. I also used the Siglent SDS2102X Plus/SDS1104X-E to analyze the IR signals. I used Altium Designer 21.4.1 and the SamacSys component libraries (SamacSys Altium Plugin) to design the Schematic and PCB. The load switching mechanism (momentary ON/OFF, toggling. Each relay can handle the currents up to 10A. The device can record up to three IR codes in the EEPROM memory and switch 3 separate devices. I have used an ATTiny85 microcontroller as the heart of the circuit. So we can use this feature in a variety of applications without buying a new IR remote control and expensive hardware, such as turning ON/OFF the lights, opening/closing the curtains. In this article/video, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads). The majority of home appliances are controlled using infrared remote controls. Infrared remote controllers are everywhere around us.
