i want an engineer a bit familiar with signal types this project is about making an arduino sketch that can read car speed and convert it to single wire signal for tachograph kienzle 1390 i don't know what signal the kienzle 1390 accepts but i'm sure it is a single wire digital signal also a different sketch for kienzle 1324 tachograph this tachograph have two wire signal i think anyway ...
