Status: in the works. Wiring and reference firmware will be published in the carpe-tech GitHub organization.
What it does#
A motion sensor triggers an RGB LED strip and plays sound through an I2S amplifier. It started life as a Halloween pumpkin, but the combination fits plenty of other builds: a doorway greeter, a display case, an alarm.
What it teaches#
Sense, then react with light and sound: one input driving two different kinds of output.
Parts (planned)#
- PIR motion sensor
- Addressable RGB LED strip (WS2812)
- I2S amplifier (MAX98357) and a small speaker
