So, I bought an arduino at HOPE. Before this i have had little to no success with electronics projects, but i seem to be getting somewhere by taking the slow and steady process. I put together a motor shield last week, and after some rather ugly hacks managed to get a motor spinning to my great enjoyment. I'm now taking apart all sorts of old spare electronics (including barely used robotics kits) to gather parts before moving on to a semi real project.
I need a reliable way to power my setup, but i have very little engineering/electrical knowledge (I'm a CS student). My current setup is as follows:
Various motors and LEDs stolen from anything i can lay my hands on
I'm thinking of getting a wired setup for development as well as a battery, as it seems that battery based setups have a lot of drain. I actually have a pretty good battery pack from my vex kit (7.2v 200mAh NiCd) which i think i can just plug straight into the arduino. As for powered, I don't think I have anything that applies.
So, whats the best way to power a simple arduino based robot? Will my old vex battery work? I want to try to find everything locally, but I live in Manhattan so I'm not really limited by my local crappy radioshack.
P.S. In case my scavenging didnt make it obvious, price is definitely a factor.
