[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.

The on period, known as pulse width, is modulated (a.k.a. changed) via the code, allowing you to control the value sent to your components. PWM pins work the same way across all Arduino boards ...

Compared to analog voltage signals or digital communication, the current loop provides several advantages. This project ...

The Arduino software environment, including the IDE, libraries, and general approach, are geared toward education. It’s meant as a way to introduce embedded development to newbies. This is a ...
