Let's Make Robots!

Arduino/ servo/ RC basics

I'll start off admitting that I'm a complete novice at robot building, so pardon me for what is probably stupid questions. I have bought an arduino with the intention of building a robot and have an idea of doing so mainly with servos, and I know that I can probably run them off the arduino without any problems helped by the arduino servo library, but can I just plug them in directly to the arduino or do I need a resistor in between or something? And question 2 How do I make my robot controllable via R/C? How do I put those circuits(?) together? I'm thinking of using some of these components: Arduino UNO

I guess I'll worry about the code later on...

Thanks for all your help in advance! Hayabusabot

Hi Chris,

Can you elaborate a little on this??  I have plugged lots of 3-wire servos to +5, Gnd and an Arduino I/O with no problem.

But I COULD be missing somethin' :-)
