CuVoodoo #016 – colourful times


use LEDs on a wall to show time progress:
The LED clock is an add-on for round wall clocks. The purpose is to have LEDs on the circumference of the clock to show the progress of the time using coloured light.

For that you will need:

  • a WS2812b RGB LEDs strip (long enough to go around the clock)
  • a development board with a STM32F103 micro-controller and 32.768 kHz oscillator for the Real Time Clock (such as the blue pill)
  • a coin cell battery to keep the RTC running (optional)
  • a GL5528 photo-resistor to adjust the LED brightness (optional)
