Hey Everyone!

In this instructable I'm going to show you how to make a WiFi enabled universal remote that you can control with your phone or computer.

I think it's a cool project that can be easily adapted or extended to whatever suits your needs.

Check out the video for a demo and quick run through what's involved in the project.

The code, hardware and circuit diagram are available on github.

Step 1: Hardware for the Project

The hardware for the project is pretty straight forward, you will need the following parts:

  • Wemos D1 Mini
  • IR LED
  • 2N3904 (Although a 2N2222 might be a better choice)
  • 330 Ohm resistor
  • IR Receiver (TL1838) - Needed for reading codes.
  • A breadboard (everything fits on a mini breadboard)

Rather than connecting the IR LED directly to the pins of the ESP8266, we need to use a transistor as a switch. This is so the IR LED can get enough current.

The rest of the circuitry is pretty straight forward.
