Video 47: CheerLights

Learn how to create an IoT CheerLights system using an ESP32 microcontroller, enabling synchronized color changes globally through MQTT communication.

• MQTT Communication: Understand how MQTT works for subscribing to feeds and receiving information, demonstrated with the CheerLights feed.

• Hardware Setup: Learn how to connect the ESP32 microcontroller with the camera extension module and WS2812 LED lights.

• Library Installation: Install necessary libraries for MQTT communication and controlling WS2812 LEDs in the Arduino IDE.

• Coding: Explore the code for setting up Wi-Fi, connecting to MQTT server, handling messages, and changing LED colors accordingly.

• Board and Port Selection: Get instructions on selecting the ESP32 Dev board and the correct port in the Arduino IDE.

• Demonstration: See a demo of the CheerLights system in action, including local and global color changes through MQTT and monitoring via the serial monitor.
