b'CODING CHALLENGESCHANGE THE DISTANCE AT WHICH YOUR ROBOT REACTS: Try changing the distance at which your robot stops and turns away from an obstacle.CHANGE THE BEHAVIOR OF THE ROBOT WHEN IT SENSES AN OBSTACLE: Try changing the code so that your robot does something different when it senses an obstacle.TROUBLESHOOTINGCheck the wiring of your motors and the way that they are The robot drives mounted to the baseplate. If one of your motors is flipped backward and/or turns around, reposition it, or switch its black and red wires on the in the wrong directionbreadboard (this will reverse the direction that it turns).You can try gently bending the pins of the distance sensor so The robot runs intothat it points straight ahead. The robot will get stuck if one obstacleswheel hits an object that it is driving past (the distance sensor wont see the obstacle unless its in front of the robot).Try installing fresh batteries. These slow or sporadic behaviors are symptoms that your robot may be running out of power. The robot drives slow Please note that the 4 AA batteries output about 6 or 7V, or not at all, though the which is just below the recommended input voltage for the RedBoard is poweredRedBoard. You can also use 9V batteries with a proper adapter, though their battery life wont last as long. Jumper wires unfortunately can go bad from getting bent too much. The copper wire inside can break, leaving an open connection in your circuit. If you are certain that your Still not working? circuit is wired correctly and that your code is error-free and uploaded but you are still encountering issues, try replacing one or more of the jumper wires for the component that is not working.105 : circuit 5c'
