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 the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

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.

Makers, looking for a project to keep them busy this weekend may be interested in a new DIY Arduino arcade game project which uses LEGO bricks and Arduino ...

As usual with Arduino, the ‘pin numbers’ aren’t the actual chip pin numbers, unless by coincidence. The led pin was correct for me, only the push button pin needed reassigning (I added a push button ...

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 ...

While you hopefully don't need one-button access to 911, a desk-mounted panic button is undoubtedly cool, and it makes for a great DIY Arduino project ...

The Adafruit Gemma measures just 1 inch in size and is powered by an ATtiny85 and programmable with an Arduino IDE over USB, allowing you to create those wearable projects of the future.

Premier space exploration disaster simulator, Kerbal Space Program, is fun to play with regular controls, but it can be improved with this DIY build that lets you launch ships with a giant red button.

Thorin Klosowski DIY musical instruments are their own thing entirely, but if you're looking for a place to start, Adafruit has a guide to building your own MIDI controller using an Arduino.
