This is a video of a breadboard of a controller to use a traffic light as the display on a countdown timer. The traffic light itself is not included in the video – only the display circuitry. I made at least three mistakes in the video. I called the start/pause button a start/reset button. I said that the button board contained resistors and diodes when I meant to say resistors and capacitors. Finally, I said there would be video of five different display colors, but there are only four; I could not get the video of the yellow display to upload.
