Tell us about yourself!
So here's what I'm going for. Break beam sensors are about 8-10 inches apart. When the beam is broken, I want the Arduino to turn on the K'nex motor until the beam is broken again. Do you think that this is possible using your setup?
I'm such a rookie when it comes to the Arduino that I feel like I'm bothering you for specifics. Nevertheless, I hope you don't mind if I hit you up for suggestions and tips over the next couple of weeks. To give you more information, I've constructed a rotating three-scene Star Wars diorama for Halloween this year that I want to have kids "use the force" to have it rotate to display each scene. I'd much rather have it be interactive than use a physical on-off switch.
Arduino + K'nex Motors
I know this is an old project post, but I noticed that you don't make use of the switch plugged into the breadboard. I'm working on a project that makes use of the Arduino with break beam sensors to turn on and off a K'nex motor. Your project is a starting point for me and I'd like to know what suggestions you may have.
