Recently I received the Particle Photon and developed a WordClock with the help of a WS2812B LED Strip.
The LEDs are cutted and arranged in a way described in the mikrocontroller.net article. The front plate and the inner grid are laser cutted by formulor.de and inserted in a 23x23cm RIBBA Frame of Ikea. Between the front plate and the inner grid is a white piece of paper to diffuse the light of the LEDs. The LEDs are glued to a Hartschaumplatte and connected to the Particle Photon. For adaptive lightning there is a LDR resistor attached.
The source code and the laser cutting template is available on Github.
Parts:
- RIBBA 23x23cm frame
- Particle Spark/Photon
- WS2812B LED strip, 60 LEDs per meter, min. 97 LEDs
- laser cutted front plate and inner grid (e.g. formulor/ponoko)
- LDR
- 10k resistor
