Servomotor mit zwei Taster Mit dem linken Taster geht der Servomotor auf Position 0°. Mit dem rechten Taster auf die Position 90°.

#include  <Servo.h>

const int KNOB0 = 2;
const int KNOB90 = 3;
const int SERVO = 9;

Servo myservo;  // create servo object to control a servo

int val;    // variable to read the value from the analog pin

void setup()
{
  myservo.attach(SERVO);
  pinMode(KNOB0, INPUT);
  pinMode(KNOB90, INPUT);
  digitalWrite(KNOB0, HIGH);
  digitalWrite(KNOB90, HIGH);
}

void loop()
{
  if(val == 89 && digitalRead(KNOB0) == 0){
    val = 0;
    myservo.write(val);
  }
  else if(val == 0 && digitalRead(KNOB90) == 0){
    val = 89;
    myservo.write(val);
  }

Steppermotor mit Treiberplatte Der Steppermotor (Schrittmotor) macht jede Sekunde einen Schritt nach Rechts. Nach 5 Sekunden stellt er sich auf die Ausgangsstellung zurück.

#define DIR 3                   // Direction Pin
#define STEP 2                  // Constant
#define BUT 4                   // Direction Button

int count = 0;

void setup(){
  pinMode(DIR, OUTPUT);         // Direction is an output
  pinMode(STEP, OUTPUT);        // Step is an output
}

void loop(){
  if(count < 5){
    digitalWrite(DIR, HIGH);    // set direction
    stepOnce();                 // Step
    count++;
  }
  else{
   digitalWrite(DIR, LOW);      // set direction
   while(count > 0){
     stepOnce();                // Step
     count--;
   }
  }
  delay(1000);

}

// Function Definition ---------------------------
// the specifications says the low to high transition
// must be at least 1 microsecond
void stepOnce(){
  digitalWrite(STEP, HIGH);
  delay(1);
  digitalWrite(STEP, LOW);
  delay(1);
}
