Hello!
This video shows how to:
- add MQTT library (PubSubClient) to Arduino IDE
- script ESP32 to connect, subscribe, and publish data to the MQTT broker (Miqottt)
- use Serial Monitor and MQTT Explorer to monitor data
- display data using Scalare*
Plug your ESP32 board into the PC and use Arduino IDE to program it.
We use Miqottt as a MQTT broker, it's free and easy to use. Please register at Miqottt.com and watch the previous video: https://youtu.be/G7tTA49Vd7w
SCALARE* is SCADA Application Software, that's also free and easy to use. Please watch this video: https://youtu.be/9izqUVRvfcw
Thanks, and have a nice day!
