我试图将加速度计读数转换为伺服运动

Question

我正在使用带有Arduino Uno的memsic2125加速度计，并试图将加速度计读数转换为伺服运动。经过一些校准后，返回正确的角度测量值（在-90到90度范围内），然后转换为0到360刻度以进行连续伺服，但伺服系统根本不会移动。我无法提供电路照片，但我相信我的布线和组件是正确的。我所拥有的程序基于http://www.arduino.cc/en/Tutorial/Memsic2125找到的程序。对不起，如果这个错误非常明显或明显，我是Arduino的新手。谢谢。

const yPin = 3;                                               //Y-axis output

  myservo.attach(9);                                          //Servo is connected to I/O pin 9

  Serial.begin(9600);                                         //Initaialize serial monitor communications

  pulseY - pulseIn(yPin, HIGH);           

  accelerationX = (((pulseX / 9.81) - 500) * 8) / 11) - 2;    //Division by the earth's acceleration
  accelerationY = (((pulseY / 9.81) - 500) * 8) / 11) - 7;    //Calculations after * 8 are for calibration purposes

  Serial.print(accelerationX);                                //Printing x and y axis degrees of rotaion to serial monitor
  Serial.print("\t");
  Serial.print(accelerationY);
  Serial.println();

  delay(100);

  servoX = map(accelerationX, -90, 90, 0, 360);               //Converting the degree measurement of the axis from -90 - +90 to 0 - +360
  myservo.write(servoX);                                      //Using the converted value and sending it to the servo as a degree of rotation
