Counter circuit with live calculation.

I require a circuit which allows two 7 segment displays (display1 and display2) to be individually set to any number between 0 and 9999. A third display (display3) is to then calculate ((display1 * 100) / display2).

The user will then be able to manually count display 1 up or down by either units of 1, 5 or 10 base on their selection.

Display 1’s value will constantly change based on the users input and display 3 should recalculate to reflect this.

Please see the image for a visual understanding of my requirements and ask any questions you may have.

I would suggest designing this circuit on two separate circuit boards, one for the user panel and one for the display panel.

Additional Requirements

• Circuit needs to be Battery powered – Battery size and type to suit circuit design.

• If possible, design without the need of a programming logic device (microcontroller or processor). However the cheapest and most reliable method should be used.

• Once you have been paid in full, the circuit design will belong 100% to myself unless other agreements have been made.

Please state what you will deliver, below are my suggestions.

Deliverables:

• Schematic Circuit Diagram.

• Circuit board layout.

• List of all materials, parts ect.. with links to item location on [login to view URL]

• Design Documentation.

• Simulation of project in video (is possible).

• Anything else you are willing to deliver.

I have attached a document with some of the parts I consider using. I would prefer all parts are sourced from [login to view URL]

Please message me with your understanding of the project, what you will deliver and an estimated time to complete the project.
