"WebLowering the Voltage. One of the easiest ways to reduce current is to lower the voltage you give to the Arduino. Just by reducing the voltage from 5V to 3.3V, the current drops from ~4mA, down to ~1mA! Reducing the voltage, does have a catch though. Reducing the system voltage too much, without reducing clock speed, could make the ... " - High vs low arduino
