SERVO MOTOR - KNOB - ARDUINO - CODE REVEAL #2

About: I just love to do electronics and robotics...

KNOB:

Control the position of a RC (hobby) servo motor with your Arduino and a potentiometer.

This example makes use of the Arduino servo library.

Supplies:

Step 1: HARDWARE REQUIRED:

Arduino or Genuino Board,
Servo Motor,
10k ohm potentiometer,
Hook-up (Jumper) wires.

Step 2: CIRCUIT:

Servo motors have three wires: power, ground, and signal. The power wire is typically red, and should be connected to the 5V pin on the Arduino or Genuino board. The ground wire is typically black or brown and should be connected to a ground pin on the board. The signal pin is typically yellow or orange and should be connected to pin 9 on the board.

The potentiometer should be wired so that its two outer pins are connected to power (+5V) and ground, and its middle pin is connected to analog input 0 on the board.

Step 3: CODE:

#include
Servo myservo;
int potpin = 0;
int val;
void setup() {
  myservo.attach(9);
}
void loop() {
  val = analogRead(potpin);
  val = map(val, 0, 1023, 0, 180);
  myservo.write(val);
  delay(15);
}
