Example program (UNO development board):

void setup(){
  Serial.begin(9600);
  pinMode(A0, INPUT);
  pinMode(A0, INPUT);
  pinMode(6, OUTPUT);
}

void loop(){
  //线性磁力传感器接A0，D6接led灯，。
  //传感器如果当作数字量开关，只N极能触发，输出低电平。
  if (digitalRead(A0) == 1 && analogRead(A0) > 540) {
    Serial.println(String("检测到s（南）磁极：数字低电平（1）  ") + String(digitalRead(A0)) + String("输出模拟值变大 ") + String(analogRead(A0)));
    analogWrite(6, 255);

  } else if (digitalRead(A0) == 0) {
    Serial.println(String("检测到N（北）磁极：数字低电平（0）  ") + String(digitalRead(A0)) + String("输出模拟值变小 ") + String(analogRead(A0)));
    analogWrite(6, 10);
  } else {
    Serial.println("未检测到磁场");
    analogWrite(6, 0);
