Story

The project to turn on the lights with the ESP8266 is an IoT (Internet of Things) project which aims to make it easier for us to turn on the lights without using a light switch, because we will only use WiFi/hotspot access and the Telegram application.This IoT project will make it easier for us to control lights remotely, making our work more efficient.

Required components:

1. NodeMCU: ESP8266

2. 2 RelayModule

3. Jumper Cables, Female to Female

4. Micro USB Cable

Software Used :

1. Arduino IDE

Installation steps:

1. Connect the microUSB cable to the NodeMCU ESP3866 port2. Connect between pins

VV -- VCC

G-- GND

D2 -- IN1

3. Connect USB to laptop.

4. ESP8266 programming uses the Arduino IDE to write and input code.

5. Then we reset the ESP 8266 by pressing the RST button on the board.

6. Open the serial monitor, and the local IP will appear, which can be accessed via the telegram application. Then open your telegram app.
