Esplora

readAccelerometer()

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.

X_AXISto read the X-axis value
Y_AXISto read the Y-axis value
Z_AXISto read the Z-axis value

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.

Example

#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);
}
