Hello I'm starting a robotics team where I work, high school so I hope my question isn't to rudimentary for this forum. I built the basic tetrix base but can't get the programming started. The robot essentially runs off of a lego mindstorms NXT module. When I try to test the sensors, or motors, nothing works, I can't even tell if they are showing up or not. I see them but can't tell if they're active. When I try to use the the schematic editor to test everything nothing seems to work. I can change the parameters, eg. motor direction, but it doesn't seem to affect the sensors, or motors plugged into the NXT. When I wave my hand in front of the ultrasonic sensor nothing changes, when I push the plunger on the touch sensor the values on the schematic editor don't change. I don't know if this has anything to do with it but I keep changing batteries but the battery indicator keeps showing the same level of power, almost dead.
