Outline
- Project：Microduino RGB LED Matrix Displayer
- Objective：Microduino RGB LED Matrix displayer is specially designed for 8×8 full color matrix, whose size is 60.5*60.5mm. The length of each light hole is 5.0mm. Therefore, you need only three pins to control 192 lights, which can be combined into any color. Besides, the displayer has PWM controlling function, capable of controlling the brightness.
- Difficulty：Middle
- Time-consuming：2 hours
- Maker：Microduino Studio-YLB

Debugging
- Get Prepared：
- to download RGB LED Matrix program and then uncompress it to the libraries folder of IDE
- to download test program “Microduino_RGBLEDMatrix”
To build the circuit of Microduino RGB LED Matrix displayer and fold Microduino FT232R and Microduino Core together on the drive board, and then fold the matrix on the board. Please note the pros and cons, which can refer to the flowing pictures.
Open the test program, you can see the experimental phenomena after successful compiling and downloading by choosing the right board.
