Example Code for Arduino-Basic Display
Please connect the circuit as shown in the Connection Diagram, then download the sample code to UNO, once uploaded successfully, the flexible display would show.
Hardware Preparation
- DFRduino UNO R3 (or similar) x 1
- 7 * 71 Flexible RGB LED Matrix x 1
- Lightboard Transfer-line x 1
Software Preparation
