| - | ===== Multiplex Switches with one Analog Input ===== | ||
| - | With an simple R-2R ladder one can build an easy multiple switch detection for an Arduino with just one analog input. That way one needs maybe some more components than in a simple resistor network but on the other hand one can just use the simple [[https://www.arduino.cc/reference/en/language/functions/math/map/|map]] and the [[https://www.arduino.cc/reference/en/language/structure/control-structure/switchcase/|switch...case]] function to detect the switch position. And additional multi-switch detection is super easy, too. | ||

| - | Unfortunately the map function didn't spread the mapped numbers even. Just the last number is assigned to the last number to map. All the others are equally mapped.\\ | ||
