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 ...

Multiplication is through an integrated phase-locked loop – which you have to remember to nurse a little for the first 100µs after switch-on to get it running properly. Even at full 8bit (256 count) ...

Frequency counters can be used, how many have a duty-cycle or m/s setting? – and measuring periods at 300kHz to 0.1% would need a very nice counter – clocking and counting at at least 300MHz. Which is ...

Most projects are built on abstractions. After all, few of us can create our own wire, our own transistors, or our own integrated circuits. A few months ago, [Julian Ilett] found a problem using th… ...

If you've got an Arduino of any variety, you might have noticed some of the pins on the board have a tilde mark or PWM printed next to them. What is PWM?

[Runtimemicro] has the answer, at least if you are writing PWM code for the Arduino. Their free application lets you set a few parameters, visually see the results, and then generates code for you.

What Are PWM Pins? The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15.
