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_AXIS | to read the X-axis value |
| Y_AXIS | to read the Y-axis value |
| Z_AXIS | to 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);
}
