Arduino cod

I have the cod but it still needs some modifications and I have the circuit simulation.
1st one is automatic you can enter the time for mixing and then enter the time for extruding by the keypad the time in minutes and then seconds
2st is manual in which you have to press the push buttons to start/stop and mixing and extruding
the LCD will display the timer countdown for the remaining time in automatic or the state when it's manual
+ there is a POT-HG to control the speed of the motor
the program should ask you first to enter the time for the mixing in minutes and then second after that the program should ask you to enter the time for extruding also in minutes and then in seconds
the LCD will display the countdown in seconds
in mixing the motor should run in clockwise and in extruding the motor should run in anticlockwise
