Esplora accelerometer example

In this example you will connect the Arduino Esplora to your PC and see the data via the serial monitor. In the picture below you can see the location of the accelerometer on the board

esplora

We will use the readAccelerometer function, here are more details about this.

Description

Reads values from the Esplora’s accelerometer. Each of the three axes are accessed independently.

Syntax

Esplora.readAccelerometer(axis)

Parameters

axis : char, determines what axis to read.

Returns

int : the value of the readings on the chosen axis. The accelerometer returns zero when it is perpendicular to the direction of gravity. Positive or negative values result when it is accelerates in one of the two directions of the axis.

Code

[codesyntax lang=”cpp”]

#include <Esplora.h>

void setup()
{
 Serial.begin(9600);
} 

void loop()
{
 int x_axis = Esplora.readAccelerometer(X_AXIS);
 int y_axis = Esplora.readAccelerometer(Y_AXIS);
 int z_axis = Esplora.readAccelerometer(Z_AXIS);

 Serial.print("x: ");
 Serial.print(x_axis);
 Serial.print("\ty: ");
 Serial.print(y_axis);
 Serial.print("\tz: ");
 Serial.println(z_axis);

 delay(500);
}

Results

You should see something like this is the serial monitor window, move your esplora and the values will change
