[Mark] from SpikenzieLabs was wrapping up a project using an Arduino the other day and found himself in need of a few more I/O pins. He could have added extra circuitry to the project, but he decided to see if he could gain a few pins by removing a few components instead.

He put together one of his Minuino boards, … Read the rest

All your I/O pins belong to ArduinoDashboard

So if you’re knee deep in an Arduino-based project and you want to constantly monitor all of the micro’s pins, what’s the best way to go about it? [Jonathan Clark] from LVL1 in Louisville was looking to keep a closer eye on his board and whipped up an application he calls ArduinoDashboard.

Programmed in Processing, the application gives you a … Read the rest
