Hii guys!! I want to measure a lipo battery's voltage with arduino. Is there a way or a tool I can use to measure other than using resistors or using https://www.motorobit.com/urun/voltaj-sensoru this tool.
I would appreciate help.
Measuring battery voltage is frequent question in forum. Lots to find if You see if You make a search. Use "Search Forum" up to the right in this window.
Yes I know. But all of them suggested voltage divider schematic. I ask if there any other way other than this
- Which Arduino. There are 5volt-logic types and 3.3volt-logic types.
- Is this a single 3.7volt (4.2volt max) LiPo cell.
- Does the battery power the Arduino, and how.

Arduino Micro. It is 2s lipo battery. Batterypowers the arduino via GND and VIN pins.
because it is a simplest way.
How else do you intend to measure 7.4v with board, that has maximum input of 5v ?
Just asking if there is any other way.
You can purchase an external voltage measure module.
But most of it will contains a voltage divider too 
Thank you
Why?
Are you concerned that it will drain the battery?

I do not want to use ressitor, I want to have like a really accurate result. But ı guess ı am going to use resistor
It is possible if the BAT voltage do not exceed an ADC max voltage of the MCU
