Your NXT Program should now does the Following

• Break to a stop

* Note the Steering Property: Makes sure you have selected the third Move block in your program. With your mouse, drag the Steering slider to the left or right. This should cause your robot to back up and turn at the same time.

7. On the Mindstorm NXT window click on the Light Sensor and note the properties on the Configuration Panel at the bottom of the window. We want the robot to go forward until the Light Sensor detects a black line and the reflected light value below the Trigger Point.

8. Change the Light: symbol form > (greater-than) to < (less-than). Now the sensor will tell the program to proceed when the senor moves over a black line causing the light value to fall less than the trigger point.

5. Change the Duration: property from, “Rotations” to “Unlimited,”

6. Next, click on the Hour Glass icon and move your mouse to the right and click the Light icon and drag it to the second position in your program. Click the Light block to place it to the right of the Move block.

3. Click the Move block with the two gears and drag it to the Start area of the program window. Click again to place the Move block. This action should select the Move icon and place it at the beginning of your program.

4. In your program you need to change the property of the Move block. To do this, click the Move block to select it. At the bottom of the program window observe the Configuration Panel associated with the Move block. Observe Move Properties such as “Duration”:
