The first block to add when you start a new project: a development board. The 'Todo' list at the bottom of the screen will remind you to add one. Development boards are under Hardware'.

The attributes of the Arduino Uno board-block are:
-
Name: By default the name is 'uno', but you can assign any name you want
-
On-board LED (on pin 13): By default 'led1' is filled in, but any other name is fine.
-
if you do not want to use the on-board LED, remove the name assigned here. You can then use pin 13 for other purposes. For example, as a System activity LED.
