Question 3:

Write a different program to make your car move forward exactly 12 inches. (Hint: use the  NXT wait for rotation, circumference of the wheel is 8 in.) Use the motor power 100 icon to set the power level to 50. Use modifiers to set the ports for the motors and the blank stop sign.



In the solution for problem 3, a different icon for the motors is used. This icon lets you use values from 1-100 for the power level. You have to add a flag to tell the port where the motor is attached. If you want to go backward, you just use negative numbers. In this problem we are waiting for to motor on port C to have turned 540 degrees.
