2. Pulse-width modulation - Wikipedia

   en.wikipedia.org/wiki/Pulse-width_modulation

   Pulse-width modulation (PWM), also known as pulse-duration modulation (PDM) or pulse-length modulation (PLM), [1] is any method of representing a signal as a rectangular wave with a varying duty cycle (and for some methods also a varying period). PWM is useful for controlling the average power or amplitude delivered by an

3. Servo control - Wikipedia

   en.wikipedia.org/wiki/Servo_control

   Servo and receiver connections A diagram showing typical PWM timing for a servomotor. Servo control is a method of controlling many types of RC/hobbyist servos by sending the servo a PWM (pulse-width modulation) signal, a series of repeating pulses of variable width where either the width of the pulse (most common modern hobby servos) or the duty cycle of a pulse train (less common today ...

   The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]

6. Servomechanism - Wikipedia

   en.wikipedia.org/wiki/Servomechanism

   A standard RC receiver (or a microcontroller) sends pulse-width modulation (PWM) signals to the servo. The electronics inside the servo translate the width of the pulse into a position. When the servo is commanded to rotate, the motor is powered until the potentiometer reaches the value corresponding to the commanded position.

7. Servo (radio control) - Wikipedia

   en.wikipedia.org/wiki/Servo_(radio_control)

   The "relative" type is the more traditional usage of PWM whereby a simple low-pass filter converts a "relative" PWM signal into an analog voltage. The two types are both PWM because the servo responds to the width of the pulse. However, in the first case a servo may also be sensitive to pulse order.
