Ok, new question, i ordered in a arduino nano. i tried to find a low power mode library or something. sadly, i couldn't find anything. Do you guys know of any ways to get lower power consumption without removing the leds? or am i better off using my Uno?

 Well the power on led is not under any kind of software control so sleeping won't do anything for it.

sleep mode will at least save a bit of power.

Kill the leds.  If you are not using the onboard regulator cut it's legs (the cheap AMS1117 regs from china have a high quiescent even if you're powering after the reg).  If you don't need the ADC, shut it down.

Rather than butchering Arduinos, why not start from an ATmega328P chip, flash it with an Arduino bootloader then program it via a USB <=> logic level serial cable?

That way you don't have to hack off LEDs or regulators and you can easily isolate the MCU to check its power consumption.

There's even a page about doing this at Arduino.cc
