Large 8×8 LED Matrix Display
Have you worked with ready-made 8×8 LED matrix as displays? They come in various sizes and are quite interesting to work with. A large readily available size is around 60mm x 60mm. However, if you are looking for a much larger ready-made LED matrix, you may be out of luck. For this project, we will be building a single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. Each of these 8×8 LED matrix modules is around 144mm x 144mm in size.
Though our display is not designed to work with any particular microcontroller, we will be using the popular arduino board in this instructables to drive it via SPI using only 3 signal wires.
