PCB LED Flower

PCB designing it is my hobby. Usually, I did something for myself only, but some time ago my wife asks me for anything beautiful for her.

And soon I designed this flower. It’s the first time I use an Attiny processor, and it was just another experiment for me.

All flower’s petals have his own microcontroller with 12 LED connected in charlieplexing order. And this microcontrollers to be controlled by 1-wire protocol.

The flower still not finished, I should write new code to control all LED separately. For now, I can only light up all LEDs simultaneously.

Before starting this project, you should know how to solder smd and how to program ATtiny microcontroller.”
