OLED Watt, Ohms, and Volt Project

[ifearclassic]

Hi,
I am in fact quite new to these forums but have been lurking for a while. I am trying to design a OLED reader that will display the watts, ohms, and volts after being read from a circuit. Almost exactly like this:
Any ideas on where to start? I am not necessarily a novice when it comes to circuits but I am no expert either. Any input on a good place to start would be great!
Right now I was looking at this: http://www.alldatasheet.com/datasheet-pdf/pdf/28026/TI/SN54LS696.html , I think this could be a vital component in creating this circuit, but once again, I would appreciate some input.
Thanks for your time.

Welcome to the PF.

Are you intending to measure the power being consumed from an AC Mains connection? It sounds like you don't have much experience with circuits, let alone AC Mains high-voltage circuits and safety...?
