Reusing LED from RC helicopter controller I have an old RC helicopter controller, but not the helicopter.  I recently purchased an Arduino Uno and would like to do something with LEDs(beside the on-board one built-in). Can I use an LED from the controller, that is already soldered in, cut it free and plug into my breadboard.

Side Note

I have no experience in soldering and don't own a soldering iron.
Yes, you can. For convenience, cut a bit shorter the lead on the side of the package where the flat part is so that you can identify the leads easier.
