Estou tentando utilizar este sketch a fim de se acender
led 1 = x
led 2 = y
led 3 = z; /* nos pinos 10, 11, 12*/
com os respectivos movimentos no ADXL 335, alguem poderia me auxiliar ?
grato !
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 = 265;
int maxVal = 402;
//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
}
