The Arduino development board has grown in popularity over the last few years and has spawned a myriad of interesting projects such as auto-lacing shoes, The EyeWriter 2.0, and the Mobile Dance Stage.

An Arduino is a microcontroller — a single board designed to control something and perform a specific task. Unlike a Raspberry Pi, you won't find anything resembling an operating system here; instead, ...

The Raspberry Pi has been the basis for many cool projects. Even so, Models A and B have been criticized for having only a handful of GPIO pins available. Sure, the new Model B+ has a 40-pin GPIO ...

An Arduino can be used to test the life of any battery with less than 5 volts, Boxall says. So, for a quick way to see how much juice your AAA, AA, C, or D batteries have left, build this ...

The big picture: If you don't know anything about electronics but have always wanted to learn and build your own IoT project, Arduino has the solution for you. The Plug and Make Kit is a comprehensive ...

With their cheap price tags, massive I/O provisions, and low power consumption, microcontrollers like the uber-popular ...

When connecting a LED to a PWM Pin of the Arduino (3,5,6 on Duemilanove) and selecting "output default high/low" in the plugin, the pin can't be set or cleared. When setting it to "PWM 500 Hz" and add ...

I always like projects that bring the Raspberry Pi and Arduino together, however gently. It's what the world needs, a bit more harmony. Check out this little one on GPIO programming on a Raspberry Pi ...

I uploaded DriverMEGA.ino sketch to Arduino MEGA board and probed GPIOs with oscilloscope. If my understanding is correct, GPIO outputs are 0s and 1s that will be fed into TC4427COA driver chip. But ...
