Ks0128 keyestudio EASY plug ADXL345 Three Axis Acceleration Module

Keyestudio EASY plug ADXL345 Acceleration Module

Introduction

The ADXL345 module is a low power, 3-axis MEMS accelerometer with high resolution (13-bit) and measurement at up to ±16g (gravitational force).
Digital output data is formatted as 16-bit twos complement, and is accessible through either a SPI or I2C digital interface.
The ADXL345 is well suited to measures the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.
Note: this module needs to be used together with EASY plug control board.

Connect It Up

Connect the EASY Plug ADXL345 Acceleration module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Below is an example code. Open or drag below code to Mixly Blocks and upload the code to your board to check the 3-axis acceleration data and the module's tilt information.

What You Should See

Open the Serial monitor to see the 3-axis acceleration data. See changes as you sway the Accelerometer.

Little Knowledge:
If you think the monitor’s result is too fast to see the data clearly, you can drag a Delay block to add into the source code. Shown below.
After that, upload the code again and open the monitor, you should be able to see the display data clearly.

Extension Experiment

Controlling Three LEDs

Hookup Guide
Connect the EASY Plug ADXL345 Acceleration module and three LED modules to control board using RJ11 cables.

Test Code
Upload the test code below to your board to check the 3-axis acceleration data and the module's tilt information.

What You Should See

Upload success, open the serial monitor, it prints out the value of X,Y,Z axis. Each axis controls a light. If the measured value is greater than 200, LED lights up.
