  • Can anyone paste example code and setup for using these with an Arduino? A description of the parts and their uses and connections would be very helpful as well.

  • I don't see what the big deal is, I'm just a guy in the background, wearing a yellow shirt.

  • A device draws as much Amperage as it requires to function, so we can only control the voltage that goes to that device. Ohm's Law is used to determine how much 'extra' voltage needs to be 'eaten up' in our circuit: Ohm, Ohm, Ohm, yummy!

No public wish lists :(
