Topic: SIK #1, 5v connection (Read 2370 times) previous topic - next topic


In the SIK project #1, the diagram shows a wire from the 5v pin on the Arduino board to the breadboard + column.  What is the purpose of this connection since it is not necessary to make the LED light up?  The LED draws its power from pin 13 (or whatever pin 0-13 you choose to connect it to).


You're correct that it is not necessary.  Perhaps it's to demonstrate the possibility of making that connection between the Arduino and the breadboard - and to get us in the habit of doing so?
