Process Work 12/12

I came into the studio early today to look at the circuit again. I connected a multimeter to it and the motors worked perfectly with the sensor just like they did the first time, but only when the multimeter was connected. I tried to get a video of it working but then it stopped just like it stopped working with our laptops. I changed the Hbridge out as well and it still wouldnt power. You can hear the motors try to turn but they dont actually power up. I know its taking too much power and I do not know of any other power source we can use. We may have to drop it down to only four motors if they are really drawing that much power.
