Thank you so much for your help. Obviously, I'm a newbie. Not quite sure what I'm doing. What does this mean exactly:
I still would need a processor, no? Not just a server driver board by itself?
Would you advise getting a Feather instead of the Itsy Bitsy? Which one? I only need to run two servos, so would I really need a processor AND a servo driver board?
Because I will need to do this quickly, I want to order everything I'll need in one order... what cords, wires, cables, sockets do I need to have on hand to connect these things that are different from the tutorial, such as this different power supply and the processor and the server driver board.
I have done some soldering in the past.
With the USB power supply I guess I'll have to modify the 3d printed box that holds the battery.
Thank you again,
Elena
