Features: ESP8266 WeMos D1 mini module which I finally found good application for (now you can buy better cheap ESPs) 6 x LEDMatrix module with MAX7219 driver supplied directly from USB port with USB plug all data are synchronized every 7-8 minutes time and date are taken from google.com weather informations are grabbed from openweather.org JSON api no hardware RTC clock is necessary internal temperature, humidity sensor (options - DS18B20, DHT22, DHT12) ESP8266 setup and control as a Wi-Fi Web Server (WiFiManager, OTA, mDNS) receives a message input from a User Input page, then displays the message on a scrolling LED matrix display. The interface for all the controls is designed as a webapp for internet browser. 6 x MAX7219 8 x 8 LED Matrix module 1 x WeMos D1 mini 1 x Interface Shield Schematic is available here: Normal: https://easyeda.com/neoseven/led-matr...
