Arduino Nano Frequency

The Arduino Nano Every has a default PWM frequency of 976.5625 Hz. This may seem like an oddly specific frequency, but it is derived directly from the 16 MHz oscillator 16 MHz 64 256 976.5625 Hz

PWM library - a powerful library that allows you to change the PWM frequency on ATmega48 88 168 328 640 1280 1281 2560 2561 microcontrollers, of which 328 is on UNONanoMini and 2560 is an Arduino Mega. Allows you to set any PWM frequency, pre-delay, TOP

This is a digital square wave where the frequency stays the same, but how often that signal is being sent is adjustable. Without context, that doesn't mean much. Pulse Width Modulation lets you do many useful things.

The pin parameter is the pin number which must be capable of generating PWM signal. For Arduino Nano or Arduino UNO the PWM pins are 3,5,6,9,10 and 11. The pins 3, 9, 10 and 11 generates PWM frequency of 490Hz and pins 5 and 6 generates PWM frequency of 980Hz. The value parameter ranges from 0 to 255 corresponding to 0 and 100 duty cycle.

Output B frequency 16 MHz 64 255 2 490.196Hz Output B duty cycle 50 255 19.6 Phase-correct PWM divides the frequency by two compared to fast PWM, because the timer goes both up and down. Somewhat surprisingly, the frequency is divided by 255 instead of 256, and the duty cycle calculations do not add one as for fast PWM.

Default Arduino Nano PWM frequency . On Arduino Nano, there are a total of 6 PWM pins available. These pins are numbered as 3, 5,6,9,10, and 11. The default PWM frequency for all pins is 490 Hz, except pins 4 and 13 whose default frequency is 980Hz.

The Arduino Nano uses the ATMega328P microcontroller, same as the Arduino Uno. Pin 11's PWM is controlled by Timer 2. By default Timer 2 has a prescale of 64 ie. setting 0x04. The base frequency of Timer 2 is 31372.55 Hz resulting in a frequency of 490.2 Hz ie. 31372.5564 490.1961.
