When it comes to microcontroller programming, it’s basically flipping switches on and off. These switches / pins we call them digital I/O pins. Consider the following example, blinking an LED for ...

Thanks to software frameworks and libraries that have become quite powerful over time, even with a compact and inexpensive system, it is possible to achieve complex functions. In this project, we use ...

The stream of PCM audio data can be copied to an audio sink in order to render the sound to a output device: In order to drive some speakers you will need an Audio Amplifier Module (e.g. a class D ...

The project is an experiment to illustrate that an Arduino can be used to create a real-time audio processing wherein the first set of examples alter an incoming audio signal to an audio output and ...

In the last installment of The GeekDad Arduino Guide, I introduced you to the Arduino hardware and why it is so cool. Now, let’s start actually using an Arduino. How do you get started? Well, first ...
