Hi all,
I’m in a project to make a robot car wich follows black lines. For this, im using:
-2 6V DC motors
-4 colorsensors (TCS230 TCS3200 kleurherkenningsmodule - Ben's electronics)
-ultrasonic sensor(the one you can find anywhere)
-MOTOR SHIELD (L293D Motor shield Arduino Uno en Mega compatible)
I’m also using a LEGO NXT battery as power supply.
The problem is, after a few seconds the motors heavily take down, and stay still. After turning the aruino off and on again, it works for, again, a few seconds. We hear the motors running all the time, but with that the voltage takes down either and gets a huge resistance.
We tried:
-a new arduino board
-added 2 batteries serial
-replacing motors(several times!)
Changing the ports of the motors pinned in the motor shield.
It all doesn’t work, so I hope someone here can help me with this specific problem. Thanks!
