I'm doing a nerf gun sentry project at school, and I was wondering if a bread board is necessary to hook up a servo to an Arduino. My group is looking at something like this:
Its going to help to have breadboard, you are going to need to supply separate power to the servo so will need to connect that somehow, you will also need to connect the ground wire from the servo to the separate power AND the arduino.
See the two links in my signature for what you can expect if you do not use separate power.
