Smart-Home-Lighting-Control-System-In-ESP-8266

This project features a Smart Home Lighting Control System built using the ESP8266 microcontroller. The system integrates an LDR (Light Dependent Resistor) for ambient light detection and an LED for lighting control.

Aim

To interface an LDR (Light Dependent Resistor) with an ESP8266 and create a system with both Automatic and Manual modes,

Components

• ESP 8266
• LDR

Connetion

• A0 ----> S
• VCC ----> VCC
• GND ----> GND

Procedure

1. Open visual studio code Create New Project,with a Framework of " Arduino"
   • We can also Interface ESP8266 microcontroller to Arduino IDE
   • In the Arduino IDE, you typically do not need to explicitly include #include <Arduino.h>
2. Interface LDR sensor With VScode And Print data on the serial Moniter For Analysing The Nature
3. Modify the program to get desired outputs on serial monitor

Code

#include <Arduino.h>
