ARDUINO CODE
/* -----------------------------------------------------------
Objective:
Read the state of a slide switch and control an LED based
on the switch position.

Components:
- Slide Switch
- LED + 100 Ω current-limiting resistor
- Arduino Uno

Working:
The slide switch outputs either HIGH (5V) or LOW (0V).
Arduino reads this digital state from pin 10. If HIGH, the
LED connected to pin 9 turns ON; otherwise, it stays OFF.
   ----------------------------------------------------------- */

const int switchPin = 10;  // Pin connected to slide switch
const int ledPin = 9;      // Pin connected to LED

void setup() {
  pinMode(switchPin, INPUT);   // Configure switch pin as input
  pinMode(ledPin, OUTPUT);     // Configure LED pin as output
}

void loop() {
  int switchState = digitalRead(switchPin);  // Read switch state (HIGH or LOW)

  if (switchState == HIGH) {
    digitalWrite(ledPin, HIGH);  // Turn LED ON
  } else {
    digitalWrite(ledPin, LOW);   // Turn LED OFF
  }
}
