First 4 flip flop uses as synchroniser. Total four state define as full Half1 Half2 Empty. These four state mapped with 00 01 10 11 and further it mapped with 4 Led. Logic circuits design to control the states using D-flip flop. Another Logic design with help of one D flip flop to control motor. Motor only start when it goes to last stage and it OFF only when water level of tank full.
Explain how to test your project: it have 3 input clock input A input B Total 5 output out1 – connect to red Led (Full) out2 – connect to yellow1 Led (Half1) out3 – connect to yellow2 Led (Half2) out4 – connect to Red Led (Empty) out5 – connect to Red Led (moto)
| # | Input | Output |
|---|---|---|
| 0 | c | segment a – Red Led (Full) |
| 1 | l | segment b – Yellow1 (Half1) |
| 2 | o | segment c – Yellow2 ( Half2) |
| 3 | c | segment d – RED (Empty) |
| 4 | k | segment e – RED (motor) |
| 5 | segment f | |
| 6 | i | segment g |
| 7 | n | dot |
