Alexa Smart Home Automation system using NodeMCU ESP8266 & Relay Module | IoT Projects

In this IoT project, I have made the Alexa Smart Home Automation system using NodeMCU ESP8266 & Relay Module. You can control lights, fans, and other home appliances with the voice command. I have used only the Amazon Alexa app to connect the Echo Dot smart speaker with the NodeMCU.

Required Components for this Alexa smart home project 1. NodeMCU or ESP32 board https://amzn.to/3fJA4EG 2. Relay Module https://amzn.to/2BQ5Y3o 3. Alexa Echo Dot https://amzn.to/2PkTOTe Required Components for Relay Module: 1. Relays 5v (SPDT) 2. BC547 Transistors 3. LED 5mm 4. 220-ohm Resistors 5. Connectors Download Code for this Alexa Home Automation projects https://drive.google.com/uc?export=do... During the video, I have shared the circuit diagram for this Alexa control home automation and also explained the code for this IoT project. This is a very simple home automation project, so you can easily make this smart home device with NodeMCU and Relay module. I have also shown how to set up the Amazon Alexa app for this smart house project. You can control up to 10 home appliances with Alexa. There is a limitation, the NodeMCU, and the echo dot smart speaker should be connected with the same wifi network.
