hello : )
I wonder if anyone can help? I've been trying to make two little circuits that are able to vary resistance and that can can be controlled from a single slider.
i've made a picture below to aid explanation. ( the orange box things in the picture are the circuits i am stuck on)
.
The two circuits vary the resistance of the two channels and work the same but opposite to each other, so when one is high the other is low and when the controller slider is central the two resister circuits are equal.
i have tried lots of things , but i am now thinking to buy a couple of vca ic's and use a transistor not gate type circuit to flip one of the channels over? But so many times people on here think of great solutions, i just had to ask first : )
thanks for any help : )
