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 ...

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.

Arduino-compatible ATtinys with more pins Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

Often, when it comes to your Arduino project,you never have enough input/output (I/O) pins on your Arduino Microcontroller. The addition of your favorite LCD display, a bunch of blinkers, beepers and ...

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.

Developers, hobbyists, Arduino or Raspberry Pi enthusiasts looking to combine both Raspberry Pi and Arduino systems in the same project may be interested in a new shield for Arduino created by ...

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?
