Getting Fancy with Sensors

[FadyS.]

Hi, we're a rookie team and we're not done autonomous mode, but since we have over 3 weeks until our regional, I'm taking the time to work on autonomous mode. Now, I don't want to go overboard with sensors for autonomous but I want to know what kind of stuff is available at a local Radioshack that may be useful to autonomous. I already picked up a few switches and a potentiometer. I may pick up another potentiometer though. Also, I might pick up a few infrared phototransistors. Are these analog or digial sensors? Any other neat gizmos to pick up? I've got to admit, I love playing around with all these sensors. Hehe, "Captain, sensors are picking up a spatial anomoly! We should shut down the warp drive!!!" lol.
