Internet Conneted Lights (NodeRED & MQTT) 💡

In this workshop we will going learn build a Internet Conncted Lights with the help of NodeRED and MQTT.

Required Hardware 🛠

• NodeMCU ESP8266
• LED’s
• Switch
• Raspberry Pi (Not mandatory)

Required Softwares 👨‍💻

• Arduino IDE
• NodeRED
• Eclipse Mosquitto MQTT Broker

Architecture

Step 1 : Connect NodeMCU and LED’s

Step 2: Install Arduino IDE and Add NodeMCU.

You can download and Install Arduino IDE from here Arduino IDE In default Arduino IDE only Support Native boards like UNO,Nano.. etc , so we need to install NodeMCU Board and MQTT Libraries .

NodeMCU Board Definition

Open Arduino IDE and add additional Board URL File => Preference (Ctrl + Comma)

In Additional Boards Manager, click add and paste the URL there http://arduino.esp8266.com/stable/package_esp8266com_index.json And click “OK”.
