Nigel Goodwin Super Moderator Most Helpful Member Apr 7, 2008 #2 Almost certainly not, usually it's used for converting a resistance (as in a joystick) to a frequency - this is how the joystick ports in a PC work. You can use a voltage to modify the output of a 555, but it's a far more limited range.
