🖥️ Code

The code is available in the stair_lighting.ino file. It is well-commented for easy understanding and modification.

📝 How It Works IR sensor detects motion at the bottom of the stairs.

The microcontroller (Arduino UNO) triggers LEDs in sequence.

Lights stay ON for a few seconds and then turn OFF automatically.

Reverse triggering can be set for descending movement.

// Example Code Snippet
if (digitalRead(sensor1) == HIGH) {
    for (int i = 0; i < numLEDs; i++) {
        digitalWrite(ledPins[i], HIGH);
        delay(200);
    }
}
