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 ...

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.

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 ...

} Enhancement Ideas Here, the three LEDs are directly connected to Arduino pins with independent current limiting resistors (R1, R2 and R3) which is enough for a basic model. But if you wish to ...

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 ...

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 ...

You can use these pins with your projects. The Arduino Nixie Tube SHIELD is now available to back via indigo go with pledges starting from $25 and shipping expected to take place during December 2017.
