Re: Electromagnet
You would need to use a power source that can supply plenty of current, so I would use a relay controlled by robovation controller (the EDU robot controller?) rather than simply take the current from the controller. As an electromagnet's strength comes from the amount of current you can pass though it, I would not recommend using the controller as the electromagnet's source of power.

PS: Be sure you don't short out the battery. Typical copper wire has a very low resistance. Don't let current run rampant through your system.
