I have no experince with code, and I only have basic electronics knowledge, but have built DIY kits in the past and can follow signal flow in a schematic, and can tell a resistor from a pot/transistor etc.
So I have been toying with an idea.
I have an analog device, that does not have memory, but I would love it to have memory:)
Could I use a pi3 with a GPIO shield to control it?
I want something like this:
Analog device control pot (pot/switch etc) send to Pi3, and then to analog device circuit board.
The pi3 would be in between.
My idea would be to take a specific pot on the device, and note its ohm value, and note if the pot was linear etc and then emulate that on the pi.
I would then desolder the pot and in its place, would place a pot that is not connected to the device, but goes directly a pi3 in port on a gpio (or similar). Then the pi3 would control a transistor (or whatever) that is connected to the solder points where the original pot was soldered in.
So basically I want the pi3 to function as a digital pot. (many pots and switches actually, about 53 total).
I *DONT* want to digitize any of the devices analog signals. I only want to control them.
What specific shield could be used?
What about the transistor thing?
Could you point me in the right direction post some links etc, pretty please:)
