What Will I Learn?

• Node-RED, the lightweight graphical programming tool.
• ESP32, the powerful low-cost microcontroller with Wifi that you can program with the Arduino IDE.
• MQTT Mosquitto broker, for reliable messaging between the ESP32 and Node-RED.
• Use any Raspberry Pi as a host for Node-RED and the MQTT Mosquitto broker.
• How to combine Node-RED, MQTT, the Raspberry Pi, and the ESP32 to create a complete automated control application.
• Use Javascript inside Node-RED to process sensor inputs and calculate actions.
