The project is to design a "seat belt safety circuit" that will comply with the following specs:
The car can only be started if:
1)The driver is seated (switch 1).
2)the drivers side door is closed(switch 2)
3)Key is in the ignition(switch 3)
4)The seat belt is buckled(switch 4)
5) The ignition key is turned on to start the engine(switch 5)
If the proper sequence of switches is not completed and switch 5 is activated, the car should not start. In this case, one should be able to return all switches to their inactive state, reset the circuit and start a new sequence.
I know that in order to do this I must use flip flops with the correct inputs, but I am not sure how to go about designing this.I might be wrong, but I believe I will need 5 flip flops in order to complete the project(one for each switch.) I must design it on multisim as well as physically build it. Any help or thoughts are appreciated!!
