How can I supply 5v voltage to circuit in a portable way?
First, if it''s really that important that this device be small and the batteries minimal, design it for 2.5-3.3 V power. Then you can use a coin cell directly. You will also find that most parts that run from this power voltage will draw less power than when running from 5 V. Second, you can convert between voltages with a switching power supply.
The Ultimate Guide to Powering Your Arduino Uno Board
Battery power allows for an operating voltage range of 6 to 20 volts, utilizing the Uno''s onboard regulator to ensure the supply is diminished to the necessary 5V for the board''s operation.
