Any idea what the use of jumper clips is? They’ve been laying in our tool box with no actual use and i’m interested in what they really do.
When placed in a digital sensor port and set up as a touch sensor, that port returns a value of 1… like a pressed button. You can use them to do anything a pressed button would to. In particular, you could select from a set of autonomous programs based on what port you put a jumper in.
I have a jumper template for RobotC. You can PM me and I’ll give it to you.
Now I know what you do during class… 
I wrote a detailed article about them that will probably be useful: VEX Sensors: Jumper Clips & LED Indicators
Oh thats not all he does…
