In this post I will demonstrate how to use an LED matrix display with Android Things. I want to use an LED matrix display for my bus stop sign project. I have been using a character LCD which doesn’t give much visual impact. LED matrix displays are big and bright and can be seen clearly from a greater distance than character LCD displays.
That’s better
Hardware
The hardware for this project consists of:
- An Android Things development board
- an stm32 development board (Blue Pill)
- 3 32×64 LED dot matrix boards daisy chained together
- a 5V power supply
