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?

PWM pins are generally used in controlling output devices in Arduino projects. To send a PWM value to a PWM-capable pin like the Mega's D9, the easiest and most common way is by using the ...

Because all the pins are shared, you have the same problem with the Arduino pins, too. If you are driving an output pin with the FPGA, you shouldn’t try to drive it with the CPU also.

Enter the ExtraCore library for Arduino, a software library that turns two or more Arduinos into a multi-core microcontroller with more pins than you’ll ever need.

A couple years ago I heard people start talking about something called an Arduino. This was before I started writing for GeekDad and my life was pretty busy with work and family so I relegated the ...

Home > Computing A brief introduction to Arduino If you've heard the term "Arduino" but never quite know what people were talking about, then this is your lucky day.

In a previous article, we looked at connecting various kinds of Arduino hardware to your Mac. Here's how to get started programming on them to create your own projects.

The Arduino Esplora is a brand new do-it-yourself gamepad being released through retail channels. This is a perfect my-first-Arduino project because it doesn't require manipulating a breadboard ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led – the green one on the left in the photo. And it has a pair of yellow leds – called TX ...
