Although it’s technically possible to get 16 bits of resolution on a ATMega328, most implementations of PWM on everyone’s favorite ‘mega – including just about every Arduino sketch – are limited to 8 ...
Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
Combining PWM with a small R-2R ladder improves both. It reduces PWM ripple significantly and increases the DAC’s resolution. In this Design Idea, an eight-resistor array and three output pins ...
Certain Microchip (was Atmel) ATtiny and ATmega microcontrollers have a handy phase-locked loop which boosts the 16MHz clock up to 64MHz for peripherals including the PWM. May 2022 update – tinyAVR ...
