The data for each axis is stored in two bytes or registers. Principle: See the schematic diagram of the Rotary Encoder module below. There is a 3. In both cases, the ADXL operates as a slave device. We will talk more about the equations for those calculations in a minute. In our case we have a three-axis design, therefore, we are interested in six points. Favorited Favorite 0. Setup The most complex part of the example code is the void setup section. By measuring the acceleration caused by gravity, you can calculate the tilt angle of the device to the level surface. Open the Serial Monitor, and wait for the prompt that says to Send any character to display values.

    applications, as well as dynamic acceleration resulting from motion or shock.
    There is no default mode if the CS pin is left unconnected, so it should always be tied high or driven by an external controller. This is a 3-axis accelerometer which can measure both static and dynamic forces of acceleration. Build the circuit. The earth gravitational force is a typical example of static force, while dynamic forces can be caused by vibrations, movements and so on.

    1. Yes, the ADXL has special sensing abilities! It is well suited to measure the static acceleration of gravity in tilt-sensing applications, as well as dynamic acceleration resulting from motion or shock.

    2. The data for each axis is stored in two bytes or registers. So if we read the value of channel B when channel A is low level, we can know in which direction the rotary encoder rotates.

    3. You'll notice an X-Y-Z axis symbol on the breakout board that will help with orienting in each direction.
