Fubarino Contest: Micro Voltmeter

recorte

This collection of hardware is a diy voltmeter. It can measure up to 17V with 1 microvolt resolution while taking seven samples per second. The LTC2400 ADC board is used to make the measurements, with the Arduino processing the output and taking care of the display and user input buttons.

In addition to showing off what the thing can do in the video after the break, [Luis] gives us a look at the easter egg he added to the project. When you have a source that is very precisely 12V, the meter will read out Hackaday.com!

Incidentally the display used in this hack is one we’ve seen before. Obviously this is a convenient way to add interactive controls to your projects.


This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
