Next, attach your LED to another digital pin (let’s say pin 9), making sure to use the resistor to prevent it from burning out. With the hardware set up, you’re ready to dive into the programming!
In your Arduino IDE, you will write a simple sketch that continuously checks for motion detected by the PIR sensor. When movement is sensed, the LED should light up, and you can even program it to stay on for a specific duration before turning off again. A basic code snippet might look like this:
“`cpp
int ledPin = 9;
int motionSensorPin = 7;
int motionState = 0;
void setup() {
pinMode(ledPin, OUTPUT);
pinMode(motionSensorPin, INPUT);
}
void loop() {
motionState = digitalRead(motionSensorPin);
if (motionState == HIGH) {
digitalWrite(ledPin, HIGH); // Turn on LED
delay(5000); // Keep it on for 5 seconds
digitalWrite(ledPin, LOW); // Turn off LED
}
}
“`
