Hi Maliha,

Sorry that you’re having trouble with your light-tracking bristlebot. I’m not familiar with this project but I will try to help.

My first suggestion is to check all of the wiring on your breadboard to make sure everything is connected properly. Next, try turning each of the potentiometers to see if you can shut off the corresponding motor. If that works, try testing the bristlebot with your torch light.

I hope this helps. Please post again if you have more questions.
