Hello
I want to make a porject that reads the voltage ,current ,frequency, of the electricity mains and display them on an LCD using a uC, i have no problem about the uC part , but little info about the signal converting ,
SO is there a chip that cant tranform such signals to the uC ,or where to find circuit schematics about this subject.
Thx

Analog Device produces Energy Measurement IC for mains.

you can also use transducers to convert them to form in which you are comfortable working with and then display it.
