“Have you worked with ready-made standard 8x8 LED matrix as displays to make scrolled text or to display your Youtube channel subscriber. A large readily available size is LED diameter 5mm. 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 colour BIG LED matrix display which is made up of a few large 8x8 LED 10mm matrix modules daisy-chained together. Each of these 8x8 LED matrix modules is around 100mm x 100mm in size.
This is a development from the instructables project before making ESPMatrix Devices.”
