If you are not familiar with Raspberry Pi, you can use Arduino to display text on dot matrix using Blynk app. For me, this tutorial is intermediate level, so, you may need to refer following tutorial first.
- Getting Started for ESPresso Lite V2.0 (To install ESP8266 board, go to Getting Started with Arduino IDE section, follow step 1 to 4)
- Displaying on MAX7219 Dot Matrix Using Arduino (For wiring connection)
- Displaying Text Message on Dot Matrix Using Blynk App and Raspberry Pi (For setting Blynk widget)
This video shows how to display text message on dot matrix using Blynk App and Arduino.
