Accelerometer Data Collection with ADXL335

Objective

This experiment uses the ADXL335 accelerometer to measure acceleration along the X, Y, and Z axes.

Required Components

• ADXL335 Accelerometer
• Arduino Board (e.g., Arduino Uno)
• Jumper wires
• Breadboard

Working Principle

The ADXL335 is a 3-axis accelerometer that measures changes in acceleration and outputs analog values corresponding to X, Y, and Z axes.

Arduino Code

/*
 * Accelerometer Data Collection with ADXL335
 * This code reads the acceleration values from the ADXL335 sensor.
 */

const int xPin = A0;  // X-axis connected to analog pin A0
const int yPin = A1;  // Y-axis connected to analog pin A1
const int zPin = A2;  // Z-axis connected to analog pin A2

void setup() {
  Serial.begin(9600);  // Initialize serial communication
}

void loop() {
  int xVal = analogRead(xPin);  // Read X-axis value
  int yVal = analogRead(yPin);  // Read Y-axis value
  int zVal = analogRead(zPin);  // Read Z-axis value

  Serial.print("X: ");
  Serial.print(xVal);
  Serial.print(" Y: ");
  Serial.print(yVal);
  Serial.print(" Z: ");
  Serial.println(zVal);

  delay(1000);  // Wait for 1 second before the next reading
}
            

Results

The serial monitor will display the acceleration values along the X, Y, and Z axes.

Applications

• Mobile device motion detection
• Game controllers with motion sensing
• Vehicle crash detection systems

Conclusion

The ADXL335 accelerometer is a useful tool for measuring acceleration along three axes, enabling applications in motion sensing, gaming, and crash detection systems.
