SUMMARY
The Arduino Uno requires a supply voltage of 5V, which can be sourced from either a USB connection or an external adapter. The microcontroller itself draws only a few microamperes (uA) of current, while the entire board typically consumes a few milliamperes (mA), primarily for powering the onboard LED. This information is crucial for ensuring proper power supply when using the Arduino Uno in various projects.
