i’m quite the beginner to electronics and arduino…
i want to mount the print head assembly of an inkjet printer as a pitch control slider to the neck of a bass guitar. In order to let arduino move the head to a desired position, it needs a convenient (cheap) way to report the current position on the neck to arduino, fretwise. one idea is… to simply have something like small contact plates mounted at each fret position (i’ll use about 12 frets) and have these connected to 12 different circuits, with the ability of the head closing each circuit individually as it passes them. now… i have no idea what to search for as a “collector” for these circuits to send a signal along the lines of “circuit n closed” to arduino. maybe i’m totally off with this solution anyway. any suggestions?
