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?
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
