STEP 6: Program Main Code

See diagram below: The main code has a forever loop that runs through three if-then switches. The first checks the left color sensor and moves back and turns if it sees black. The second checks the right color sensor and moves back and turns if it sees black. The third checks the ultrasonic sensor and charges 100% power if it sees the enemy. Regular movement is  forward at 50% power.
