ADXL345 Accelerometer Interface With Arduino

The ADXL345 is a small, thin, low-power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16g [1, 2].

Components Required:

• ADXL345 Accelerometer 
• Arduino
• Jumper Wires
• Power Supply / Data Cable

Source Code:

	#include <Wire.h>
	#include <Adafruit_Sensor.h>
	#include <Adafruit_ADXL345_U.h>
	Adafruit_ADXL345_Unified accel;
	void setup(void)
	{
	Serial.begin(9600);
	Serial.println("Accelerometer Test");
	if(!accel.begin())
	{
	Serial.println("Ooops, no ADXL345 detected ... Check your wiring!");
	while(1);
	}
	accel.setRange(ADXL345_RANGE_16_G);
	// accel.setRange(ADXL345_RANGE_8_G);
	// accel.setRange(ADXL345_RANGE_4_G);
	// accel.setRange(ADXL345_RANGE_2_G);
	}
	void loop(void)
	{

	Serial.print(event.acceleration.z);
	Serial.print(" ");
	Serial.println("m/s^2 ");
	delay(500);
