We are creating a remote control that can switch on and off any TV by sending infrared signals. It is a simple and quick project that needs a ProTrinket, an IR LED and a resistor. As we are currently waiting to get our hands on the new ProTrinkets we have ordered, we are using an Arduino Uno to test the code and prototyping. And guess what? it works!
The final device will be a ProTrinket with a LiPo battery, an LED and possibly a switch or a button to operate it.
