Hi all, I am brand new to the forum and to arduino. I am currently and quite successfully working my way through Make's Getting Started With Arduino book until now. I am on example 06B and I am having difficulty with setting up the circuit. Based on the sketch it is an analog setup but the book says to set up the LED circuit based on figure 5-4 which uses the digital pin 9.
Can anyone give me direction on how to properly set up this circuit?
