I am attempting to put together my first project and I wondered if anyone can tell me how I go about attaching servos to an Arduino and what happens if I need more inputs than are available?
Thanks for the links. 
I see that this has been posted as solved, but I thought to reply… I’m using the SSC-32 servo controller from linxmotion (not sure if I"m allowed to say that on here though)… but it allows up to 32 servos to be controlled with just 2 pins connected to the Arduino. That might be worth a look?
I"m using it in my ROVer robot project (links below) and I had the same issue… needing the flexibility to add more stuff over time and worrying about running out of capacity.
What are you planning for your first build? Cheers,
Nick.
