Came up with the idea

After working from home for about 6 months, I wanted a way to let my two young children know that I was in a meeting, and I couldn't be interrupted. We tried hanging signs on the door, but that didn't work. Then, I thought about a "do not disturb"/"on air" light. What if I could turn on a light when I was in a meeting?

I work on the second floor of my house, and the rest of my family spends most of their time downstairs. I didn't want to have to walk downstairs to turn on and off a light, so I started investigating how to control a light from my computer - specifically, when my camera was on.
