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 ...

Code explanation On the first line we set a variable pinButton with an integer value of 8 (the pin number on Arduino Board where we connect the button or switch). Then in the void () function we set ...

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 ...

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 ...

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.
