Today we setup the #PiPico hardware and #Zig to start part 1 of 4 in which we will develop the Simon says game.

Today we will make the hardware and test the LEDs making a #knightrider LED scanner using the 4 LEDs.

I do this in 4 episodes of 20-30 minutes to avoid one big video and overload the viewer with too many details. Each episode focusses on some core aspect.

The code in the episode:
github.com/rdoetjes/simon_zig/blob/main/simon/simon_1.zig

The repository
github.com/rdoetjes/simon_zig.git
