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);

    }

<ins>/!\ </ins> Attention aux pins PWM, certaines sont en FAST PWM et d'autre en Phase-Correct PWM. (https://www.arduino.cc/en/Tutorial/SecretsOfArduinoPWM)

Bon cablage!
