TV Remote with CircuitPython

Build your own IR remote using QT Py RP2040 and CircuitPython! The LED arcade button can be programmed to transmit just about any IR signal.

NeoPixel Status

The LED illuminates when the arcade button is pressed and the QT Py's on-board NeoPixel LED turns on, letting you know the IR signal has been sent. The NeoPixel color switches from green to red.

Embedded Electronics

All of the electronics are housed inside a snap fit case. The QT Py RP2040 is secured to a quarter-sized Perma-Proto via headers making it modular.
