The objective is to transmit water from tank 1 to tank 2
Control of water motor for tank by using logical gates and "d filp-flop"
Which the first voltage source(6v) is a switch locate at lower level of the water tank 1
And the secound voltage source(6.5v) is a switch locate at higher level of water tank 1
And the third voltage source (5v) is a switch on tank 2
