OK OK OK
a pic can do anything a 555 can.
Again...
I ask how the right way to do this task of using a PIC to
control the resistance and capacitance of external circuits... for a real good reason.
There are lots of example circuits that show how to build discrete component projects. There must be a 1000 of them out there.
BUT
when I want to do a PIC controlling project to interface those circuits... I don't really find ANY examples.
So...
I ask here if anybody knows a good way to make the
replacement circuitry to interface a PIC where a resistor or capacitor is found in a circuit....
because its the resistors and caps that are always attached to dials with pots and variable caps.
Forgetting the 555....its all those other circuits I want to learn to interface.
I just used the 555 as the example because there are sssssssssssoooooo many web sites devoted to showing the 555 pins layout...where plus and minus and ground lays compared to the pins....so anyone could find good references.
