Calls to the Arduino core analogWrite() function take almost 5 microseconds. This function automatically takes care of pin initialization and is very robust and safe while sacrificing speed. This ...

This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...

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 the ...

When multiple PWM converters are connected in series (or in parallel) in a power electronics circuit, it is appropriate to run all converters at the same frequency but with certain phase shift among ...

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 ...
