I think it&#x27;s just the same placement as the breadboard layout. But yeah, it doesn&#x27;t really help understanding.<p>BTW for anyone copying this onto a breadboard, I&#x27;ve never seen one where the busses are split like the picture. Make sure your 5v and 18v aren&#x27;t actually connected! Perhaps by building in the middle of the board if the bus is split there.
