I am trying to build a digital pot but I am not sure exactly what components to use. I am trying to build a circuit that has a varying resistance on two, two output circuit leads.
I have a 555 I can use for a clock pulse
I have 2 resistor network 16pin dips isolated
I also have misc ics 4011, 4081, 4017, 4001
Resistors, diodes, caps and stuff.
I may have some relays too
I also have a basic stamp but if I don’t have to use it I will prefer not to.
I want it to switch automatically when I turn it on. I can add a reset too.
I think I got everything I need, I am just not sure how to make the resistors switch together.
Thanks for any help
