EV3 Activity 2.1 (Adding a start button to your program)
In this lesson you will add a touch sensor to your program that will act as a start button. You will do this by adding a wait block to the beginning of your program. The wait block needs to be set up correctly. You will need to select touch sensor, compare, and state. This sets the wait block to wait until the touch sensor is pushed. Which means the program will wait indefinitely until the sensor is pushed. Notice the number at the upper right corner of the wait block. This is the touch sensor that is being used. You can click on it and change it to the other sensor if you want. Finally add a move block after the wait block and have it move from the start line to the finish line and stop with the tires on the line. If you look back at your program for activity 1-1 you will find the value that you should use.
