I have successfully used a 4511 IC to make numbers 1-9 appear on a 7 segment led display, cool.
Now how can I use this to say have it display a number for a set voltage? Example a 12v fan, I make a circuit that gives 3v, 6v, 9v and 12v. Have 4 switches one for each of the voltage taps. So then how can I use that 7 segment LED display to show speed 1,2,3,4 which would correspond to the related voltages?
