WebMar 17, 2024 · This equates to a duty cycle of 5% to 10% at 50 Hz. Now, if the pulse is at 1.5 ms, the servo motor will be at 90-degrees, at 1 ms, 0-degrees, and at 2 ms, 180 degrees. In summary, by updating the servo with a value between 1 ms and 2ms, we can obtain a full range of motion. In electronics, duty cycle is the percentage of the ratio of pulse duration, or pulse width (PW) to the total period (T) of the waveform. It is generally used to represent time duration of a pulse when it is high (1). In digital electronics, signals are used in rectangular waveform which are represented by logic 1 and logic 0. Logic 1 stands for presence of an electric pulse and 0 for absence of an electric pulse.
