Remote Controlled Car Project Software

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

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

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

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

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
