Components and supplies

Adafruit 32x32 RGB LED Matrix Panel - 6mm pitch
Should come with the 16-pin ribbon cable.
×1
Ph a000066 iso (1) ztbmubhmho
Arduino UNO
×1
Prototype Board
Might want to get some extra boards as a precautionary measure. Board has to be cut down to size.
×1
22 AWG Wire
very little wire was actually used for this project. approx 1-2 feet should get you there.
×1
Double-Row Header Pins, Break-Away: 20 pcs (40 pins in total)
Only need 16 individual pins for this project, but extra never hurts.

Necessary tools and machines

09507 01
Soldering iron (generic)
Solder
Dremel w/ Cutting Wheel
For cutting prototype board down to size.

About this project

I needed a way to connect my arduino to my led matrix while avoiding the unsightly mess of jumper wires. This need became apparent while I was in the middle of another larger project, so I guess this is a project nested inside of another larger project lol. My connections and wiring had to be neat & clean because the larger project was "wearable tech."

here's the jumper wire connection that needed attn:

Use the following references out of Adafruit's guide to map your connections. There IS a slight variation in 16x32 and 32x32 matrices, so pay extra special attention. You might also need to edit the constructor line of code depending on which matrix you have.
