PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor.

– More PWM channels: For Motors, Robotics, Actuators and more! – More ADC channels: Monitor more sensors! – A second SPI bus: Simplify wiring – More GPIO: for when your running short on pins ...

The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

I routed the first PWM channel out to J3 on the edge of the iCEStick so I could connect a scope probe to look at the real results. Below you’ll see the output at 50% (40 hex) and 12.5% (10 hex).
