Automated Closet Lighting

After building a rack for my workout shoes a couple of weeks ago, I wanted to tackle another thing about the broom closet that has been bugging me for years. It never had a light! I put together a rough video of the entire process.

I’m really happy with how it turned out, especially since I was able to use parts I had in my electronics collection. The whole thing uses a simple circuit, cost less than $10, and doesn’t require WiFi or any fancy connections.┬áThe Working of Transistor as a Switch page on Electronics Hub was a big help. I ended up using a PNP transistor in my circuit without resistors because the LEDs were dimming and I wanted maximum brightness.
