Stap 4: Stap 3: de Servo-Code
Op de servo-code veranderde ik de servo van 180 graden, tot 45 graden te draaien. Dit is dus toen de servo is helemaal naar links of naar rechts, het wiel niet alleen te achter de RC auto slepen is.
Servo-Code:
/* Controlling a servo position using a potentiometer (variable resistor) by Michal Rinott modified on 8 Nov 2013 by Scott Fitzgerald http://arduino.cc/en/Tutorial/Knob */#include Servo myservo; // create servo object to control a servoint potpin = 0; // analog pin used to connect the potentiometer int val; // variable to read the value from the analog pinvoid setup() { myservo.attach(9); // attaches the servo on pin 9 to the servo object }void loop() { val = analogRead(potpin); // reads the value of the potentiometer (value between 0 and 1023) val = map(val, 0, 1023,0, 45); // scale it to use it with the servo (value between 0 and 180) myservo.write(val); // sets the servo position according to the scaled value delay(15); // waits for the servo to get there }
