I had this, not working, ceiling lamp that collected dust. And I was wondering what to do with it and I found a way how to turn it into artwork.
And it's relatively easy to do if you have access to some technologies like laser cutting and printing. The picture is printed under plexiglass.
The radar sensor detects movements and the microcontroller (MCU) changes the RGB LEDs colours to react to human movement. And if the is no motion at certain time lights will turn off.
Three main components are:
- Microcontroller, with 5V logic. Like Arduino Nano.
- NeoPixel type RGB LED stripe.
- RCWL-0516 microwave radar sensor.
