# Motion Sensor Lamp Project
Welcome to the Motion Sensor Lamp project! 🌟
Experience the magic of creating your own motion-activated lamp using a PIR sensor, LED, resistor, Arduino, and a breadboard. Let's dive into the details of how to set it up and bring this project to life! 🚀
## Components Needed
- PIR (Passive Infrared) Sensor
- LED 💡
- 220 ohm Resistor
- Arduino Board 🛠️
- Breadboard 🔌
- Connecting wires 🧵
## Circuit Connection
Follow these steps to connect the components:
1. Connect the **5V** from the Arduino to the **positive line** of the breadboard (`🟥 red wire`).
2. Connect the **GND** from the Arduino to the **negative line** of the breadboard (`⬛️ black wire`).
3. Connect the **GND** (Ground) pin of the PIR sensor to the **negative line** of the breadboard (`⬛️ black wire`).
4. Connect the **Power** pin of the PIR sensor to the **positive line** of the breadboard (`🟥 red wire`).
5. Connect the **Signal** pin of the PIR sensor to **Digital Pin 2** of the Arduino (`🟨 yellow wire`).
6. Connect **Digital Pin 13** of the Arduino to the **anode (+)** of the LED (`🟩 green wire`).
7. Connect one end of the **220 ohm resistor** to the **cathode (-)** of the LED.
8. Connect the other end of the **220 ohm resistor** to the **negative line** of the breadboard (GND) (`⬛️ black wire`).
Now that your circuit is set up, let's move on to the code implementation!
## Arduino Code
```cpp
int pirsensor = 0;
void setup()
{
pinMode(13, OUTPUT); // Set digital pin 13 as an OUTPUT
pinMode(2, INPUT); // Set digital pin 2 as an INPUT for PIR sensor
}
void loop()
{
pirsensor = digitalRead(2); // Read the value from PIR sensor connected to pin 2
if (pirsensor == HIGH)
{
digitalWrite(13, HIGH); // Turn on the LED if motion is detected
}
else
{
digitalWrite(13, LOW); // Turn off the LED if no motion is detected
}
delay(10); // Delay for stability
}
```
## Usage
1. Upload the provided Arduino code to your Arduino board.
2. Power the circuit by connecting the Arduino to a USB port or an external power source.
3. Place the PIR sensor in a location where it can detect motion.
4. When motion is detected, the LED will illuminate, creating your motion-activated lamp! 💡
Enjoy experimenting with this fun and practical project. Happy making! 🛠️
