Task 2 – Sensor-Based Simulation

📄 File: IoT_Sensor_Simulation_Proteus_LDR_LED.pdf

Topic: Light-Controlled LED using LDR Sensor (Arduino Uno + Proteus ISIS)

A complete sensor-based simulation document designed specifically for Proteus ISIS, demonstrating an automatic LED switching system using a Light Dependent Resistor (LDR).

Circuit Overview:

5V ──→ LDR ──→ A0 (Arduino)
              │
           10kΩ Resistor
              │
             GND

Pin 13 ──→ 330Ω ──→ LED (+) ──→ LED (-) ──→ GND

Arduino Code Logic:

int ldrPin = A0;
int ledPin = 13;
int threshold = 500;

void loop() {
  int lightValue = analogRead(ldrPin);
  if (lightValue < threshold) {
    digitalWrite(ledPin, HIGH);  // Dark → LED ON
  } else {
    digitalWrite(ledPin, LOW);   // Bright → LED OFF
  }
  delay(200);
}

Document includes:

• Proteus-specific component names for part search
• Step-by-step .hex file generation workflow (Arduino IDE → Proteus)
• Full circuit diagram with wiring connections
• Line-by-line code explanation
• IoT sense → process → act concept explanation
• 4 screenshot instructions for simulation validation
• Troubleshooting section for common Proteus issues

Expected Simulation Results:

LDR Condition	Analog Reading	LED State
Bright light	> 500	OFF ❌
Dark / covered	< 500	ON ✅
