I decided to build traffic light for my kid.

I have played with addressable led many times and it’s my preferred go to LED if I can – just from the ease of use, mainly if you have more then two-three.

So I took a bit of cardboard and formed and painted a traffic light top, took parts from a clipper lighter to make the hoods.

Next step was to create the board, I used a digispark inspired board, which allow me to program the ATtiny85 directly via a USB cable without the need for external SPI programmer nor FTDI.

I used this two tutorial on the way:
