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).
