Introduction
Make a 7x8 led matrix using WS2811 led strips.
Theory
Building the box
Wiring
Be careful to wire +5V to +5V (I broke one led). Soldering the leds is manageable: add the solder to both the led connector and to the wire, the attach the wire to the led connector and warm it using the soldering iron.
-
Programming. No +5V is needed.
-
Running only.
