One problem with all those Arduino variants is, that the pins are different between them. Most of the example sketches are written for the Uno, which is the most common variant. And often the pin ...

Program to test the digital and analog pin I/O header pins. The program checks that the inputs and outputs correctly drive static voltage levels. This is useful if you buy a secondhand Arduino or ...

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.

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?

We previously used multiplexing technique in Arduino to interface 4-digit 7-segment display and driving 8x8 LED matrix. Charlieplexing allows you to control N * (N – 1) LEDs, where N is the no of pins ...

In this tutorial we discussed the Sound sensor, its pinout, working, and how to interface it with Arduino. This article includes a complete Arduino code and circuit diagram along with a step-by-step ...

The new Arduino IDE 1.6.2 features a one click install of boards and libraries and now includes two new menu items in the form of “Sketch > Include Library ...

The official Arduino team responsible for the development of the official range of Arduino hardware and software, have this week announced the availability of the latest Arduino IDE 1.6.9 software ...
