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?

For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino Leonardo, Micro or Pro Micro) Arduinos have hysteresis built into the input side of digital IO pins (as ...

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 ...

The Arduino is an open hardware platform designed to make prototyping easily accessible. The design allows for other people to modify, expand, and improve on the base, and many people have started ...

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 ...

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.

A clever Maker builds a servo-powered, Arduino-controlled robot arm to crack the PIN on a GPS unit.
