I wanted to track my webcam state, whether or not it is in use, so I could turn on an On Air light. The light's on when my webcam is in use. I use this for my new remote working world. I am in Microsoft Teams and Zoom meetings most of the day.
When this Python script runs, it checks if my webcam is in use or not and updates a ThingSpeak channel with the status. Then, an ESP-8266 Wi-Fi device reads that state from ThingSpeak to control a light.
