Messchieber auslesen, Digitalanzeige und Bluetooth, DRO Caliper

Here you can see a project for reading out the data from a digital caliper gauge. It uses the 24 bit format. I use an atmega8, but an arduino (M328) would work as well. For the 7-segment displays I us two shift registers HC595. A bluetooth module is also connected, so you can see the data on a smartphone or PC (serial connection) Software status: q&d Source code on github. https://github.com/berred16/DRO-calip...
