If you wanna build a fancy led matrix display with only a few pixels, this is exactly what YOU need!
Step 1: Get all what you need!
You need:
-An Arduino
-WS2812(B) LED strip
-A piece wood
-7 jumper wires
-7 female pin headers
-some capacitors
-some wires
Step 2: Craft it to one part
Use your crafting tools to bind the led’s onto a base (something like a piece of wood or something else of your favor). Arrange them in a matrix of a size like 5 by 10 Led’s.
I added on every second line an capacitor, because the LED’s need much power. And I don’t put the data out to the data in of an other line, because I wanna drive them parallel on 5 IO pins.
Put the first line’s data IN to D10 of the Arduino, put the second to D9, the third to D8, the fourth to D7 and the fifth to D6!
