Nodemcu NTP clock with Max7219 LED matrix
Hardware parts
Software dependencies
This uses the Arduino IDE with the esp8266 core and the following libraries, installed using the Libraries manager:
- ezTime 0.8.3, to get time from NTP pool, properly format it and take in account timezones
- MajicDesigns's MD_MAX72XX library 3.2.1, to write hours on the Max7219 LED matrix (this builds mostly upon the MD_MAX72xx_PrintText sample)
