This week we show you the different options that are available for the NKK Smart Switches.  We have all of the different versions that are available to purchase and show you each and describe a little about each.

We also show you a controller that was built over the weekend to control a script scroller for a live show Mike did the sound engineering for.  I used 2 of the NKK lighted switches that we are using in our switcher.

We also go back a few episodes to when we made an Arduino Leonardo emulate a keyboard and a mouse.

/*############################## SCRIPT SCROLLER ###############################
       This sketch uses 2 lighted NKK pushbuttons to send the keys needed to
       up and down arrow through a script for dramas.
