Servo Motors
The position of the servo motor is set by the length of a pulse.
The servo expects to receive a pulse roughly every 2milliseconds.
If that pulse is high for 1 millisecond, then the servo angle will
be zero, if it is 1.5 milliseconds, then it will be at its centre
position and if it is 2 milliseconds it will be at 180 degrees.
The end points of the servo can vary and many servos only turn
through about 170 degrees. You can also buy 'continuous' servos
that can rotate through the full 360 degrees.
Open the 'sweep' sketch and try reducing the delays from 15
milliseconds to say 5 milliseconds. Notice how much faster the
servo turns.
Try modifying the 'knob' sketch so that instead of taking the servo
angle from the position of the knob, it takes it from the Serial
Monitor, so that you can control the servo from your computer.
Hint: to make your sketch read the number of degrees from the
Serial Monitor, you can use the function
Serial.parseInt(). This reads a number from the Serial Monitor.
Servo Motor Working Principle
Before understanding the working principle of servo motor we should
understand first the basic of servomechanism.
Servomechanism
A servo system mainly consists of three basic components - a
controlled device, a output sensor, a feedback system.
This is an automatic closed loop control system. Here instead of
controlling a device by applying the variable input signal, the
device is controlled by a feedback signal generated by comparing
output signal and reference input signal.
