Menyalakan Lampu Pakai Tepuk Tangan

Introduction

This tutorial will guide you through the process of creating a hand-clap activated lamp. Using simple electronic components and coding, you can control a lamp with just a clap. This project is not only fun but also a practical introduction to basic electronics and programming.

Step 1: Gather the Required Materials

Before starting the project, ensure you have the following materials:

• Arduino board (e.g., Arduino Uno)
• Microphone sound sensor module
• Relay module (for controlling the lamp)
• A lamp (220V)
• Jumper wires
• Breadboard (optional for prototyping)
• Power supply for the Arduino

Step 2: Understanding the Wiring Diagram

Refer to the wiring diagram to set up your components correctly. Follow these connections:

1. Connect the microphone sound sensor to the Arduino:
   • VCC to 5V
   • GND to GND
   • OUT to a digital input pin (e.g., pin 7)
2. Connect the relay module:
   • VCC to 5V
   • GND to GND
   • IN to another digital pin (e.g., pin 8)

Use Fritzing software for a visual representation, which can help you avoid wiring mistakes.

Step 3: Assemble the Components

Follow these assembly steps:

• Secure the microphone sensor and relay module onto the breadboard if using.
• Connect jumper wires between the Arduino and the components as per the wiring diagram.
• Ensure all connections are firm to avoid interruptions during operation.

Step 4: Write the Code

You will need to upload a code to the Arduino. Here’s a simple example to get you started:

const int micPin = 7; // Microphone pin
const int relayPin = 8; // Relay pin

void setup() {
  pinMode(micPin, INPUT);
  pinMode(relayPin, OUTPUT);
}

void loop() {
  int soundValue = digitalRead(micPin);
  if (soundValue == HIGH) {
    digitalWrite(relayPin, HIGH); // Turn on the lamp
    delay(1000); // Keep the lamp on for 1 second
    digitalWrite(relayPin, LOW); // Turn off the lamp
  }
}

Tips for Coding

• Make sure to adjust the delay based on how long you want the lamp to stay on.
• Test the sound sensor sensitivity and adjust as needed.

Step 5: Install the Lamp

To connect your lamp safely:

• Use the relay module to connect the lamp to the power source (220V).
• Ensure all connections are insulated and secure to prevent electrical hazards.
• Verify that the relay is rated for the voltage and current of your lamp.

Step 6: Test the System

After assembling everything:

1. Power on the Arduino.
2. Clap your hands to activate the sound sensor.
3. Observe if the lamp turns on as expected.

Conclusion

Congratulations! You have successfully built a hand-clap activated lamp. This project helps you learn about sensors, relays, and basic coding with Arduino. For further exploration, consider adding features like adjusting sensitivity or using multiple sound commands. Enjoy your new interactive lamp!
