Pick Board & Port, Then Upload
Choose the right board and serial port to flash code.
Two Settings First
Before uploading, the IDE needs two answers: which board you have and which port it is plugged into. Set these once and you are ready. 🙂
Plug It In
Connect the Uno with its USB cable first. The board's power LED should glow, showing the computer is feeding it electricity.
