W05 – Browser MQTT wrap

Last exploration of color passing with MQTT. Most of class was ocmmited to theme for community AND reading reflections.

MQTT part 2 :: Browser to browser

Weekly code from github.

Examples of color passing via the browser. By default this is using a the public shift instance. You should take the time to connect to the class instance or to your own.

This shiftr intro will cover the instance variables you need to connect to different shiftr brokers. You will need to check D2L for the class broker token, please do not share it outside class.

This post covers browser color sharing with MQTT and shiftr in detail. [class code] [cleaned up, example code]

A simple hello world of MQTT — not looked at in class will reinforce the concepts for connecting to shiftr explored above. [code]

First ESP32/Feather Code Samples

We will cover this in detail in W06.

W05_2_mqtt picker — this code sample connects the ESP32 feather to MQTT and a browser to MQTT and allows LED colors selection from the web interface.
