2. The Arduino IDE

2.1. Before running the first program

Everytime we want to program a different board, we need to tell the IDE where to find it and what kind is.

Select Board Type Arduino UNO

Under the Tools menu, find the Board submenu and navigate that to select Arduino (Genuino) UNO.

Select Correct Serial Port

Under the Tools menu again, find the Port submenu and choose the one your board is connected to. Some tips to find out which is which:

  • The name of your board may appear next to it.
  • Unplug the Arduino and see which one disappears from the list.
