Vending Machine Consider the construction of a vending machine's logic. Assume that every soda costs a quarter, and that the machine accepts only quarters. • E = True indicates the machine is empty, it has no more sodas • s = True indicates the user has made a selection 2 •P = True indicates the user has paid a quarter The machine may send two control commands to its machinery: • V = True indicates machine will give the user a soda (i.e. "vend") •R = True indicates machine will return the user's quarter The machine should return a user's quarter only when they have paid and the machine is empty. The machine should give a soda only when a user has paid, made a selection and the machine is not empty. i Write a truth table for V and R in terms of E, S, P ii Write an expression for V in terms of E, S, P using boolean operators V, ^, ¬ iii Write an expression for R in terms of E,S, P using boolean operators V, A, ¬

Conclusion From your life experiences, list 3-5 examples of products that you have used that contain combinational logic. Throughout this activity we used switches for the circuit inputs and a probe for the circuit outputs. Though this works fine for testing purposes, it is not practical for real-world applications of combinational logic circuits. List three input and three output devices that would be used with real world applications of combinational logic. Going Further – Optional As mentioned in the purpose section of this activity, combinational logic circuits can be implemented with a variety of different logic gates. One such gate is called the NAND gates (see below). Functionally, the NAND gate is an AND gate with its output inverted. The picture added goes here Using what you know about the AND gate and Inverter gates, complete the truth table for the NAND gate. A B C 0 0 0 1 1 0 1 1…
