I'm just getting to grips with having my Pi control a couple of servo's and i'm looking to make an appropriate plug and play board for the GPIO header to sort the power & signal from a standard 3 pin servo connector.
I know little about components and have no idea what i'm looking for on the RS or Farnell websites to do this so was hoping someone could help and prehaps show me what to order? please?
Essentially i want a connector to plug onto the GPIO header, resistors or something to buffer the servo's and a male 3 pin connector for the other end to plug the servo's onto.
I also need a little advice on how i add in an external power source to run the servo's without blowing up the Pi. I assume battery live to servo, negative to battery ground & Pi ground?
