Instructions | Firmware for Boxclock from build-yours.de

1

Get a kit.

You get a piece of wood with the schematic engaved into it. The Electronics and wires as well as a box, dividers to prevent crosstalk between the leds and two overlays for the wordclock. The firmware only works for the word clock, so that decision is easy.
2

Glue and solder everything together.

Glue the led stripes to the wood. Make sure the led stripes are oriented in a way so that they snake up the board. Do not change their position.

The Wemos D1 is glued with a big splasch of hotglue to the wood.

Solder the led stripes together:

VDD -> VDD

GND -> GND

Dout -> Din

After that solder the begining of the led stripe to the Wemos D1:

VDD -> VDD

GND -> GND

D4 (Wemos D1) -> Din (led stripe)
3

Put it in the box.
4

Add light blocking divider between LEDs
5

Put Overlay on Top. Close the Box.
6

Start Arduino IDE. Load these two Libraries.
7

Open wordclock.ino and set your Config. Flash!

The RGB code sets the color with which the pixels will light up.
Flash the firmware to the MCU and you are done.
