In this video, I provide a complete tutorial on how to assemble your own stair lighting, featuring block diagram, code overview, testing and final layout. Code and schematic can be found on this page.
In this video, I show how I solved my hourly hydration problem by wiring a transistor to a water pump behind my desk. I describe three different ways of switching: MOSFETs, BJTs and relays. I then skim over logic gates and show how I added lighting to my bedroom.
