A WiFi-enabled RGB LED strip controller
A while ago, two unrelated things happened: I got one of those cheap RGB LED strips from Ebay, and I became interested in hardware hacking. If you aren’t familiar with the LED strips, they’re basically a long string of LEDs connected to a controller that usually supports an infrared remote control, which can be used to set the color and intensity of the lights.
When I started tinkering with hardware, I noticed a change: I started looking at common, everyday things around the house and thinking “I bet I could put a controller in that and write an API for it”. This led to a button that orders food when pressed, a rotary mobile phone, a wifi-enabled room fragrance sprayer (I haven’t written that one up, it was too simple), a self-driving RC car
