Hi. I want to be able to display on an lcd screen the savings from having certain appliances off.

So basically the way I want to do is have

-a signal which lets me know the appliance is on/off.

-a counter which will let me know how long the appliance has been off

-an lcd display to show the savings after some simple calculations have been performed

I am just not sure of what the simplest way to implement is. Do I use an fpga?
