Multiplexer Schematic

How would be the schem diagram of a vending machine(circuit) with using only (JK/SR/D/T) flip flops basically?

We are to create the Schematic Diagram of a vending machines operational circuit. I don’t have any idea about it. I would gladly accept any ideas or answer that anyone can share. Thanks. *if possible, i want to see the schematic diagram itself, using only JK or SR flip flops with some multiplexers and decoders* thank you XD

This is intended as an exercise for you, as this would be much more likely as a microprocessor solution. Here are a few steps:
List the actual steps involved in vending. This may be:
Indicate – ready to insert a coin
Wait for coin
Coin inserted
Check the coin
Coin Ok release the product
Rejected coin etc etc…
This list can be used to make a flow diagram. Depending on what you have learned, it will be a state machine or a sequencer. It will relate to your lectures. Go from there.
You are using clocked logic? Or is it boolean? You need a coin sensor with valid output for valid coins connected to inputs, maybe a lamp or two to indicate the state or progress, a solenoid or motor to drive the product release gate and a return chute for rejected coins. I would expect to set a latch when a valid coin is detected for example.
