Product Description

Description:
Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors – the holy grail of accelerometers. The ADXL335 is a triple axis accelerometer with extremely low noise and power consumption – only 320uA! The sensor has a full sensing range of +/-3g.

There is no on-board regulation, provided power should be between 1.8 and 3.6VDC.
Dimensions: 0.7×0.7″

Test Code:

//Analog read pins

const int xPin = 0;

const int yPin = 1;

const int zPin = 2;

//The minimum and maximum values that came from

//the accelerometer while standing still

//You very well may need to change these

int minVal =270;

int maxVal =440;

//to hold the caculated values

double x;

double y;

double z;

void setup(){

Serial.begin(9600);

}

void loop(){

//read the analog values from the accelerometer

int xRead = analogRead(xPin);

int yRead = analogRead(yPin);

int zRead = analogRead(zPin);

//convert read values to degrees -90 to 90 – Needed for atan2

int xAng = map(xRead, minVal, maxVal, -90, 90);

int yAng = map(yRead, minVal, maxVal, -90, 90);

int zAng = map(zRead, minVal, maxVal, -90, 90);

//Caculate 360deg values like so: atan2(-yAng, -zAng)

//atan2 outputs the value of -π to π (radians)

//We are then converting the radians to degrees

x = RAD_TO_DEG * (atan2(-yAng, -zAng) + PI);

y = RAD_TO_DEG * (atan2(-xAng, -zAng) + PI);

z = RAD_TO_DEG * (atan2(-yAng, -xAng) + PI);

//Output the caculations

Serial.print(“x: “);

Serial.print(x);

Serial.print(” | y: “);

Serial.print(y);

Serial.print(” | z: “);

Serial.println(z);

delay(100);//just here to slow down the serial output – Easier to read
