This collection of hardware is a diy voltmeter. It can determine up to 17V with 1 microvolt resolution while taking seven samples per second. The LTC2400 ADC board is utilized to make the measurements, with the Arduino processing the output as well as taking care of the screen as well as individual 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 extremely exactly 12V, the meter will checked out out Hackaday.com!
Incidentally the screen utilized in this hack is one we’ve seen before. undoubtedly this is a convenient method to add interactive controls to your projects.
This is an entry in the Fubarino Contest for a possibility at one of the 20 Fubarino SD boards which Microchip has put up as prizes!
