Hey guys,
I'm new to robotics but picking it up pretty fast

I am currently waiting on the last of my parts to arrive for the $50 robot, so bugging to get started on that.. But while I wait I'm designing / planning what i'm going to build next..
I was wondering, are there any tutorials etc. on electronics / circuits I can read & learn, on what sort of capacitors/resistors/regulators etc. that you would need in a circuit for multiple Servo's & sensors ?
So example:
If I'm building say a quadruped robot and I have 3 Servo's per leg, how many resistors and what sort would I need for the project.
I'm just throwing Idea's around so any tutorials / information would be much appreciated !

Cheers guys!
PS: Sorry if there is a topic already posted on the forum I haven't searched, if you could redirect me to it, that would be excellent.
