These sensors measure acceleration in 3-axis (x,y,z).

#Adxl345 turn on arduino i2c example portable

All these sensors are portable and can be fitted in any kind of device like wearables. They can be classified on the basis of precision, power consumption, and interfacing.

There are many types of MEMS accelerometer sensors available in the market. You can see all the accelerometer-based projects here. Hand Gesture Controlled Robot using Arduino.We used the accelerometer to build various useful applications which you can check at below links: These small sensors are used in cars and bikes to detect accidents to deploy the airbags and are also used in mobile phones for a variety of applications like compass and location tracking. Here we are discussing about ADX元45 Accelerometer which is used to measure the acceleration or change in velocity in x, y, and z-axis. There is a sensor like MPU6050 which has both accelerometer and gyroscope and it works as an Inertial Measurement Unit (IMU) to find the orientation, position, and velocity. A gyroscope is used to measure angular velocity that uses the earth’s gravity to determine the orientation of the object in motion. While Accelerometer can measure linear acceleration, the gyroscope can help find the rotational acceleration. If(adxl.We all know about accelerometer and gyroscope, they are primarily used to detect acceleration. Do not call again until you need to recheck for triggered actionsīyte interrupts = adxl.getInterruptSource() getInterruptSource clears all triggered actions after returning value * Look for Interrupts and Triggered Action */ This may come in handy when it doesn't matter when the action occurs. You may also choose to avoid using interrupts and simply run the functions within ADXL_ISR()

* UNCOMMENT TO VIEW X Y Z ACCELEROMETER VALUES */ * Accelerometer Readings and Interrupt */Īdxl.readAccel(&x, &y, &z) // Read the accelerometer values and store them in variables declared above x,y,z attachInterrupt(digitalPinToInterrupt(interruptPin), ADXL_ISR, RISING) // Attach Interrupt Turn on Interrupts for each mode (1 = ON, 0 = OFF) This library may have a problem using INT2 pin.

This chooses the pin on the ADX元45 to use for Interrupts. Accepts only 1 or 2 values for pins INT1 and INT2.
