Supplies

  1. Raspberry Pi Pico W
  2. Compatible Power Pack
  3. Breadboard
  4. LED Matrix
  5. 4 pin power connector
  6. Female DC Adapter
  7. Adafruit APDS-9960 Gesture Sensor
  8. 16 pin-to-socket jumper wires
  9. 5V4A Power Supply


Step 1: Setting Up Power Supply

  1. Strip the wires from 4-pin power connector
  2. Twist exposed wires and slide into adapter
  3. Black Ground wires into the negative port and red power going into positive
  4. Screw adapter tight to create a secure connection

Step 2: Connecting Pico to Matrix

Use the 16 jumper cables to connect the input port on the matrix to the breadboard

The matrix should provide a pin map for the HUB-75 pin locations

Provided is the map for the Pico locations for this specific code

Step 3: Attaching Gesture Sensor

Finally connect the APDS9960 sensor to the breadboard

Attach the Blue SDA wire to GP16 and Yellow SCL to GP17

Black goes to ground

Red to 3v Power

Step 4: Code

Below is the code file to get it running. For proper results, ensure that all libraries are downloaded. The gesture sensor can be a bit finicky so you may have to mess around with its directions to sync with the pixel movements on the matrix.
