A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use to turn on and off an external light like an led or relay for bigger loads.

Sometimes when you’re making a PCB that you plan on programming over USB, but you only plan on plugging in a couple of times, it would be nice to make that connection without another BOM ...
