This is why the first and third servo signals sent different pulses using identical commands.
For example: Use Digital Input block to adjust the motor shaft position depending on the external control signal or signals. As your rotate the potentiometer, its resistance changes.
The Servo library supports up to 12 motors on most Arduino boards and 48 on the Arduino Mega. The model will now be deployed to the Arduino hardware. Examples Knob : Control the position of a servo with a potentiometer.
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 board.
Task 4 - Control the Servo Motor Position via a Potentiometer In this task you will set the position of the servo motor shaft manually, using a potentiometer. This, and other potential issues can be avoided if microseconds are used instead of angles in degrees, or if the optional pulse width floor and ceiling parameters are defined in pin setup for each servo.
Select the Hardware Implementation pane and select your required Arduino hardware from the Hardware board parameter list.
