Sketch¶

Voici le sketch utilisé pour l'atelier :

int motor1P1  = 2; 
int motor1P2  = 3;
int motor1PWM = 9;
int delai     = 2000;
void setup() {
    Serial.begin(9600);
    pinMode(motor1P1, OUTPUT);
    pinMode(motor1P2, OUTPUT);
    pinMode(motor1PWM, OUTPUT);
}

void loop() {
    delay(delai);
    forward();
    delay(delai);
    backward();
    delay(delai);
    stopMotor();
    delay(delai);
}

void forward() {
    int i =0;
    digitalWrite(motor1P1, HIGH);
    digitalWrite(motor1P2, LOW);

    for(i=0; i<255; i++) {
        analogWrite(motor1PWM, i);
        Serial.print('speed');
        Serial.println(i);
    }
}

void backward() {
    int i =0;
    digitalWrite(motor1P1, LOW);
    digitalWrite(motor1P2, HIGH);

    for(i=0; i<255; i++) {
        analogWrite(motor1PWM, i);
    }
}

void stopMotor() {
    digitalWrite(motor1P1, LOW);
    digitalWrite(motor1P2, LOW);
}
