We don't need no stinkin' badgeries!

A project log for USB Caliper HID

Uses a Trinket Pro to provide an USB HID keyboard interface to a commonly available digital caliper

Lou CabralLou Cabral 01/03/2015 at 04:400 Comments some point, I reread the guidelines for the Trinket contest -- "must be battery operated".

Anyway, long story..short, the HID module will operate from a battery (if you bother to plug one in), but it will operate off of the USB bus just file.

You can ignore any reference of battery stuff in the write-up -- unless you're a stickler for details.
