I want to get and set values for a motor potentioneter
ALPS RK16812MG from a raspberry pi. I found a similar approach here however, the answers in that forum suggest a different wiring with an additional power source. Also, in that thread, there is no wiring for reading the potentiometer value.
- Can the
L 293 D, mentioned in that thread, also take care of reading the current potentiometer value or do I need another A/D converter there?
- Could you give me an example on how to wire everything properly with an additional power source
- (and, maybe you could explain to me, what this "optical decoupling" is, that the thread is talking about)
