Arduino Mega read data from USB I´m completely new to the arduino and not used to work with it. Due to an project I need to know the best way to transfer Data to my Arduino Mega. The transferred file will be an sliced 3D object. Is it possible to use the built in USB port to read from a stick? Or do I have to use a PC to transfer my data?
Please help me to answer this question since I have no clue how to manage to get the sliced file to my Arduino.
The Arduino Mega doesn't support USB-host, so you can't connect a USB stick directly.

The easiest way is to connect it to a computer, and send the data over the serial connection.
