两相四线步进电机程序

这里是一个简单的两相四线步进电机程序，使用 Arduino 控制器编写：

int coil_A_1_pin = 8; // Coil A, pin 1
int coil_A_2_pin = 9; // Coil A, pin 2
int coil_B_1_pin = 10; // Coil B, pin 1
int coil_B_2_pin = 11; // Coil B, pin 2

void setup() {
  // 设置引脚为输出模式
  pinMode(coil_A_1_pin, OUTPUT);
  pinMode(coil_A_2_pin, OUTPUT);
  pinMode(coil_B_1_pin, OUTPUT);
  pinMode(coil_B_2_pin, OUTPUT);
}

void loop() {
  // 步进电机正转
  digitalWrite(coil_A_1_pin, HIGH);
  digitalWrite(coil_A_2_pin, LOW);
  digitalWrite(coil_B_1_pin, HIGH);
  digitalWrite(coil_B_2_pin, LOW);
  delay(1000);

  // 步进电机停止
  digitalWrite(coil_A_1_pin, LOW);
  digitalWrite(coil_A_2_pin, LOW);
  digitalWrite(coil_B_1_pin, LOW);
  digitalWrite(coil_B_2_pin, LOW);
  delay(1000);

  // 步进电机反转
  digitalWrite(coil_A_1_pin, LOW);
  digitalWrite(coil_A_2_pin, HIGH);
  digitalWrite(coil_B_1_pin, LOW);
  digitalWrite(coil_B_2_pin, HIGH);
  delay(1000);

  // 步进电机停止
  digitalWrite(coil_A_1_pin, LOW);
  digitalWrite(coil_A_2_pin, LOW);
  digitalWrite(coil_B_1_pin, LOW);
  digitalWrite(coil_B_2_pin, LOW);
  delay(1000);
}

这个程序通过交替地激活两相四线步进电机的两组线圈（A组和B组），来实现正转、停止和反转操作。在每个操作之间都有一个1秒的延迟。具体的操作顺序和延迟时间可以根据具体需求进行修改。
