![](/files/-Lwvp3XrqKeMwJfsI8F5)

## 專案說明

使用「科易KEYES Arduino UNO R3 開發板」連接「兩路L9110S馬達模組」, 每2秒鐘轉動馬達一次。

此**兩路L9110S馬達模組**包含於「[洞洞兩教學材料包 Education Kit 002](https://www.robotkingdom.com.tw/product/rk-education-kit-002/)」內。

## Arduino 程式

5號、6號接MOTOR-A，9號、10號接接MOTOR-B。將5號、6號、9號、10號腳位的依序給不同的PWM訊號，每2秒鐘轉動馬達不同方向一次。

產生出的 Arduino 程式如下

```c
void setup() {
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
}

void loop() {
  analogWrite(5,0);
  analogWrite(6,255);
  analogWrite(9,0);
  analogWrite(10,255);
  delay(2000);
  stop();

  analogWrite(5,255);
  analogWrite(6,0);
  analogWrite(9,255);
  analogWrite(10,0);
  delay(2000);
  stop();

  analogWrite(5,0);
  analogWrite(6,255);
  analogWrite(9,255);
  analogWrite(10,0);
  delay(2000);
  stop();

  analogWrite(5,255);
  analogWrite(6,0);
  analogWrite(9,0);
  analogWrite(10,255);
  delay(2000);
  stop();
}

void stop() {
  analogWrite(5,0);
  analogWrite(6,0);
  analogWrite(9,0);
  analogWrite(10,0);
  delay(2000);
}

```
