Step 3: Wiring Up the Matrix Ribbon Cable to the Arduino

Picture of Wiring Up the Matrix Ribbon Cable to the Arduino

To wire up the matrix to the Arduino, I went through this handy guide from Adafruit. For convenience, I pasted the diagram and pinouts into a document and printed a quick reference page to use while wiring everything up.

Take care to ensure the tab on the connector matches the one in the diagram.

Alternatively, for a cleaner circuit, you could use the RGB matrix shield that AdaFruit sells for these panels. If you use the shield, you will need to solder in a header or wires for the phototransistor.

This looks very cool! Anyone want to try making a simulated Chladni Plate with this?
