IoT project using ESP01 ESP8266 Arduino Cloud & Google Assistant control Relay 2025

In this ESP8266 project, I have explained how to make an internet of things project using ESP01 ESP8266 Arduino IoT Cloud, Google Assistant and manual switch. You just need ESP-01/01s relay v4.0 and ESP01 to make this IoT based home automation project. To try out the Altium Student Lab, click here - https://www.altium.com/in/yt/techstudycell To try out the Altium365, click here - https://www.altium365.com/yt/techstudycell I have covered following topics in the ESP8266 Arduino IoT project: 00:16 Quick demo on ESP01 Wi-Fi control relay. 02:03 Required components of ESP8266 IoT project. 02:26 Circuit for Programming the ESP-01 using FTDI232. 02:47 Source Code for ESP8266 ESP01 Arduino cloud. 03:09 Set up Arduino Iot Cloud for the ESP8266 ESP01. 07:27 Circuit for connecting all the components with ESP01 relay. 07:58 Connect Google Home with Arduino Cloud. Required Components for the ESP-01 IoT project: 1. ESP-01 2. ESP-01/01s relay v4.0 module 3. switch and socket Amazon India Affiliate links: ESP-01/01s relay v4.0 module: https://amzn.to/45xsTcT ESP01 Module: https://amzn.to/3E6BC72 Amazon United States Affiliate links: ESP-01/01s relay v4.0 module: https://amzn.to/43ctD5J Important Link: Arduino IoT Cloud Sign Up: https://cloud.arduino.cc/ Previous Videos: Tutorial on Programming ESP-01: https://youtu.be/Tv2RMlIxBXs Source Code for this ESP8266 IoT project: https://iotcircuithub.com/wp-content/uploads/2025/02/Code_ESP01_ArduinoIotCloud_1Relay.zip Important points: 1. You don't need any Google nest/Echo Devices for this project. 2. Relay is connected with GPIO-0 of ESP01. 3. You can't monitor the feedback as switch is not connected with ESP01. 4. Here I have used Active-LOW relay. 5. Connect the GPIO-0 with GND before programming ESP-01. **Please take proper safety precautions while working with high voltages. For this project, you don't have use any custom design PCB During the internet of things tutorial video, I have explained how to program ESP01 using FTDI232 USB to TTL serial converter and Arduino UNO. Also explained the circuit diagram and how to configure Arduino IoT Cloud for ESP8266 ESP01. If the ESP01 is connected with WiFi then you can control the relay from anywhere in the world from Google Home and Arduino IoT Remote app, otherwise you can use manual switch to control the appliances. #iotprojects #esp8266 #homeautomation ------------------------------------------------------- Thanks For Watching... ✅ SUBSCRIBE ✅LIKE ✅SHARE ✅ COMMENTS Find out more such projects: https://iotcircuithub.com/ Facebook: https://www.facebook.com/techstudycell/ Instagram: https://www.instagram.com/techstudycell/ Telegram: https://t.me/techstudycell/ ------------------------------------------------------- ------------------------------------------------------- WARNING: This video is for demonstration and educational purposes only.
