We are approaching Christmas and you want to show a nice and tiny ticker tape to the front window of your house?
The project you will find here is the one you're looking for. You simply need
- a NodeMCU 1.0 (ESP 12-E Module which is basically behaving like an ESP8266)
- a Max7221 8*32 LED display
- 5 dupont jump wires (typically female to female)
- a micro USB to USB cable plus AC adapter or AC adapter with micro USB plug
- the 3 code files you can find in this repo
The main code file "mqtt_scrolling.ino" shows in lines 11 to 16 how to connect the NodeMCU to the display.
You need to edit file "credentials.h" to enter your personal credentials.
This repo assumes that you have a cloud MQTT broker which is reachable from your WLAN.
You can either set the parameters for the ticker using node-red (import the flows from file "node-red-flows.json") or any other MQTT publishing client (on your smartphone or freely available clients like MQTT.fx or MQTTX).
