I am wanting to design a simple unit that controls relays to active a 12v motor(pump). I want to be able to display the volume of the tank on an LCD, preferably TFT so I don't have to add additional buttons. The volume will be calculated from time which the pump is on. I would like to use a 4.3" LCD and does not need to be multicolor. Does anyone have any suggestions where to start?
