Power supply

The Arduino MEGA microcontroller operates over a voltage range of 7-12V, thanks to its on-board voltage regulator, while the microprocessor operates at 5V. In normal operation, the microcontroller consumes up to 45mA (if no power is supplied) and can accept a maximum current of 40mA on each of its IO pins.
