Hey Guys,
I have built an state variable filter module which includes NP/LP/HP/BP outputs.
The project I have built calls for a 1P4T rotary switch to choose which filter output is selected.
I would like to change this to not use a mechanical switch and instead use a momentary push button with which each press should select the next output. on my panel I would like an led to show which filter mode is selected.
So 1 momentary pushbutton switch and 4 led's to show which input is switched to the output.
I'm thinking something like a 4066 would do this, but havent been able to find any circuits out there to show me how it would be done. of course I'd like to keep the circuit and component count as simple as possible.
any advice would be appreciated.
thanks
