Arduino Accelerometer (ADXL330)

Another toy I ordered quite awhile ago was an accelerometer.

Just hooked it up, no sweat. Here’s the code:

#define xPin 5
#define yPin 4
#define zPin 3
int x = 0;
int y = 0;
int z  = 0;
int delta = 0;
void setup() {
  Serial.begin(9600);
}
void loop() {
  delta = x + y + z;
  x = analogRead(xPin);
  y = analogRead(yPin);
  z = analogRead(zPin);
  delta -= x + y + z;
  Serial.print(x);
  Serial.print(", ");
  Serial.print(y);
  Serial.print(", ");
  Serial.print(z);
  Serial.print(", ");
  Serial.println(abs(delta));
  delay(500);
}
