  21. Remote Controlled Car ProjectSoftware

  22. Software 1 • When 8 is pressed the car should go forward • When 5 is pressed the car should stop • When 0 is entered the program should exit

  23. Software 1: Answer var key : string (1) loop getch(key) if key = “8” then parallelput(1) elsif key = “5” then parallelput (0) end if exit when key = “0” end loop

  24. Software 2 Add to the previous program commands that will instruct the car to go: • Forward/left when 7 is pressed • Forward when 8 is pressed • Forward/right when 9 is pressed • Stop when 5 is pressed • Reverse/left when 1 is pressed • Reverse when 2 is pressed • Reverse/right when 3 is pressed • Exit program when 0 is pressed

  25. Software 2: Answer loop getch(key) if key = “7” then parallelput(5) elsif key = “8” then parallelput (1) elsif key = “9” then parallelput (9) etc

  26. Software 3 • Write a program so the car will auto parallel park • Add computer controlled turn signals • Add reverse lights • Add light sensors so the car will follow a light source
