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
To sweep a servo with an Arduino, connect the servo's VCC (red wire) to 5V, GND (black/brown) to GND, and signal (yellow/white) to a PWM-capable pin (e.g., Pin 9). Use the Servo library to control movement. The code below gradually moves the servo from 0° to 180° and back in a loop.

[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] The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment ...
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 ...
ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
Pmods come with a standard 6-pin interface of 4 signals, one ground and one power pin. Double and quad Pmods also exist. These duplicate the standard interface to allow more signals to pass through to the module. Pmods can use either SPI, I 2 C or UART protocol. With I 2 C it is possible to use a 4-pin connector. Alternatively the pins 1 to 4 ...
