Matrix_Display

A simple Matrix Display programmed in Arduino C for NodeMCU ESP8266.

Features:

  • You can upload and update texts shown on the Matrix Display wirelessly by connecting to the AccessPoint created by the NodeMCU
  • The data uploaded to the NodeMCU is stored in the internal EEPROM hence it is not lost after a power cycle.
  • You can make minor changes to the code and can cascade to multiple Matrix Displays.

Prerequisites:

  • Arduino IDE with esp8266 boards added to the preferences and boardmanager.
  • NodeMCU 8266 or any ESP8266 boards with enough pins.
  • A couple of 8X8 LED Matrix Displays with MAX7129 Display Drivers.
