Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023. On an Arduino UNO, for example, this yields a resolution

The Arduino Uno is based on an ATmega382P microcontroller. This chip has two 8-bit timers, driving two PWM channels each, and one 16-bit timer, driving the last two channels. You cannot increase the resolution of the 8-bit timers. You can, however, put the 16-bit

Description analogWriteResolution() sets the resolution of the analogWrite() function. It defaults to 8 bits (values between 0-255) for compatibility with AVR-based Arduino boards. The 86Duino’s CPU includes twelve 32-bit PWM timers, each of which allows a PWM

If you set the analogReadResolution() value to a value higher than your board’s capabilities, the Arduino will only report back at its highest resolution, padding the extra bits with zeros. For example: using the Due with analogReadResolution(16) will give you an approximated 16-bit number with the first 12 bits containing the real ADC reading and the last 4 bits padded with zeros .

Например: после вызова analogWriteResolution(16) на Arduino Due, при отправке 16-битного значения 12-битному ЦАП функцией analogWrite() будут использованы только первые 12 бит, остальные же 4 бита будут отброшены.

ESP32 can generate PWM on all IO pins. In the ESP32 analogWrite will not work, is different than the Arduino Uno. ESP32 uses 8, 10, 12, 15-bit resolution for PWM generation PWM value. Arduino Uses 8-Bit Resolution i.e.PWM range is 0-254.

PWM Resolution (Teensy LC, 3.0 – 3.6) Normally analogWrite(pin, value) is used with the value between 0 to 255, which corresponds to 8 bit resolution. Writing 256 forces the pin always high. Teensy LC &x:w, 3.x support an analogWriteResolution(bits) function

If more resolution doesn’t improve the project in a meaningful way, perhaps the investment is not justified. In fact, adding layers of cost and complexity for no particular reason is something to avoid. Putting Meaning to Arduino Resolution. Possible Output

Note that at the time of writing, the commonly used analogWrite Arduino function was not yet available for the ESP32 Arduino environment support [1]. Thus, we will

digitalWrite will set the specified pin to one of two states – HIGH/LOW, which equate to 5v (3.3v on some boards) and ground respectively. analogWrite can vary by the type of output used. If applied to a PWM pin – it will set the pin to a periodic high/low signal, where
