Making a COVID warning light

This post is designed for beginners at Linux and circuits. If you’ve done a project like this before, maybe just skip to the code.

With COVID-19 on the upswing again, I thought it would be nice to build a small appliance that could tell me how bad it is outside, without having to look up the local statistics. Here’s what I used:

  • 1x Raspberry Pi Zero W
  • 1x 8GB micro SD card
  • 1x red LED
  • 1x yellow LED
  • 2x 200 ohm resistor
  • 1x breadboard
