Description
This circuit I used the 555 timer IC in Astable multivibrator mode Pulse Width
Modulated signal usually with a frequency of 50 Hz (ie 1 ms time period) or 25 Hz
(40 ms time period). The servo angle varies according to the signal on time (which
is also known as pulse duration or pulse width.)
Potentiometer can be used to control the position of the servo. It produces a
Positive pulse between about 0.9 milliseconds and 2.1 milliseconds. The off time
between pulses is about 40 milliseconds.
