Question

Design a digital system that will count the number of switches activated and display that count in binary using LEDs. An LED that is illuminated represents a '1' and an LED that is off represents a '0'. Note that you may utilize ANY chips in your part kits to implement this design.( basic 2 input and, or, xor, xand, gates)

For this design, you will need to complete the following objectives:

_____ Interface 6 switches to your design

_____ Interface 3 LEDs to your design

_____ Provide evidence that the circuit can safely drive these LEDs

_____ Document your design process with all circuit diagrams

_____ Provide any boolean logic, truth tables, karnaugh maps

_____ Build the digital circuit necessary to implement this logic

The above mentioned method is based on the analogy that the output is binary considering number of switches in on state doing this with K maps becomes quite complicated as it comprises of 6 inputs thus the above solved simple equations can be drawn in to a boolean diagram.
