1) Shopping list

The gear led requires :

• one Led matrix  8×8 (Amazon UK, Amazon USA)
• GX12 connector 3 pin (Aliexpress)
• 4 DIN7991 M4x20 screw (included in the screws kit for the gearbox)
• 2 DIN791 M6x10 screws
• Wires and Dupont connectors (Already present in the main list)

2) Wiring

The Wiring is simple : There is 3 pins on the PCB :

• the 5V goes to 5V
• GND (ground) goes to the ground
• Din (DataIn) goes to D16 of the arduino (but it can be configured in the code)

3) The code

In the code, you just need to :

1 – Activate the LedPanel : replace  //#define LEDPANEL by#define LEDPANEL

2 – You can eventually change the data pin by changing  #define LEDPANELPIN 16

4) 3D files
