SMART LAMP PROJECT USING ARDUINO

A Smart Lamp automatically turns on or off based on the light in the room. Using a photoresistor,
it detects whether the room is dark or bright. If it’s dark, the lamp turns ON and if it’s bright, the
lamp turns OFF. This makes the lamp smart and energy-efficient.

COMPONENTS USED
The different components used in the project are:
Arduino Uno: A microcontroller that processes input from the photoresistor and controls
the bulb.

Photoresistor: A light-sensitive component that changes its resistance based on the amount
of light it receives.

Bulb: A light source that turns on or off, controlled by the Arduino.
Resistors: Components that regulate the flow of electricity to protect the circuit and control
voltage.
Jumper wires: Wires used to create connections between components and the Arduino.

Arduino IDE for coding: The software used to write, simulate and upload the code that controls
the Arduino board in Tinkercad.
To make a smart lamp project, follow these steps:

Step 1 Connect one end of the photoresistor to the 5V pin of the Arduino using a green
jumper wire.

Step 2 Connect the other end of the photoresistor to one end of the resistor.
Step 3 Connect the other end of the resistor to GND using a black jumper wire.

Step 4 Connect the junction between the photoresistor and the resistor to pin 7 on the
Arduino using a yellow jumper wire to read light levels.

Step 5 Connect one end of the bulb to GND using a red jumper wire.
Step 6 Connect the other end of the bulb to one end of a resistor (set limit 160Ω).

Step 7 Connect the other end of the resistor to pin 8 using an orange jumper wire.
