Resistors

The Bodac is a system that allows to implement several buttons on a single analog input, with the possibility to have several buttons pressed at the same time. The “usual” systems (resistors ladders or matrix without diodes), do not allow to press several buttons at a time.

The benefit of the Bodac compared to a button matrix with diodes is a simpler wiring: a resistance between each button pin, and a single wire between each button.

This pack of 1% precision resistors allows to create a Bodac with 5 buttons or less.
