Just bought my first Arduino
September 24, 2009
Senior year (undergrad) Computer Engineering major here with way too little real world electronics experience. I'm taking a microcontroller class where we're programming PIC chips in Assembly and I've always secretly wanted to be able to build robots, but was always intimidated by the idea of learning uControllers.
After finding this website and doing a little programming in class I got motivated to buy a setup and learn how to do this stuff. Woo!
I bought the basic Arduino USB board and some bare breadboard. I have plenty of electronics lying around and have a pretty good grasp on all that - but I've never had to learn very much about actually driving circuits with batteries since I've pretty much always had a power supply on a bench in the labs - that'll be an adventure.
One question I have is about small DC motors & servos - where can I buy them, how cheap can I hope for them to be, and what should be the minimum rating(s) I should look for for the Arduino Light-seeking robot (http://letsmakerobots.com/node/2164)? I know the OP just used RC car parts but I don't have much lying around and think it might be cheaper to buy proper parts.
