Discover how to produce a multiple output arbitrary signal generator cheaply and quickly with low-cost, hobbyist-level microcontroller development boards.

There’s a perception that the Arduino, as an example, is somehow easier to program. It is easy to program, primarily due to the many libraries with documentation and example code.

Why buy an expensive oscilloscope, spectrum analyzer, or signal generator, when you can simply download one for free?

In this tutorial, T.K. Hareendran shows us how to set up an interleaved PWM output on an Arduino Uno. He then uses different techniques to validate that the desired result is achieve.
