Hi everyone, I'm new using the arduino products so that's why I need your help. I have a proyect where I have to measure the AC voltage from transmissions lines with an arduino UNO and I don't know how to start. Can someone give me any guide from a code?
Transmission lines ? What is the maximum voltage you expect to measure ?

Google search for "stealing power from transmission lines" and you will find a whole bunch of ways to remotely access the transmission line voltage. Then use a full wave rectifier and measure the resulting DC voltage.
The real hard problem in your project is calibration.

This kind of questions are kinda scary. Normally anyone even getting near a power transmission line should be a certified electrician working for the power company that owns the transmission line. That kind of people should also know how to safely measure the voltage of such a line, and have access to the equipment to do just that.
Unless OP simply uses the wrong terms, and is thinking of household mains power, which is readily measured with commonly available voltage sensor modules.
Do it like the big boys use a transformer to translate to a voltage you can use, then you need to rectify it, filter it then read with the A/D and then do you math and conversion. Try this link: http://www.ti.com/lit/an/snoa682/snoa682.pdf
