LCD Menu controlled without any button

Hi,

Is anyone here has ever think about a LCD Menu we can navigate through with only one analog information of a ultrasonic sensor ?

Using time measurement and distance of hand from the ultrasonic sensor should provide enough informations level to navigate throught LCD menu no ?

you just defined another thing as trigger / button whatever. A button is just a sensor with two values OK, most buttons :slight_smile: But the idea is cool as it will look like magic a bit ..
