10x5 RGB LED Matrix With Only 5 IO Pins

If you wanna build a fancy led matrix display with only a few pixels, this is exactly 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

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!

This is the software which you need:

-Arduino

-Processing

Flash the software to your Arduino and open the processing project with... Processing! Now you should change the line "String portName = "/dev/ttyACM~";" to your Serial port, on WINDOWS "String portName = "COM~";"
