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?

When working with Arduino boards for the first time, you're bound to make some mistakes, but these are some of the most common pitfalls you can avoid.

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 ...

Using the analog converter input function of a compact microcontroller’s input pins to read ternary logic encoding allows two pins to sense as many as nine configuration states. When designing ...

Arduino peripherals, including Arduino shields, sometimes take up multiple I/O pins and leave little room to create a project that requires multiple Arduino peripherals.
