If you are in the Venn Diagram between having an Arduino and wanting a Banana Piano then this is the product for you.
Not just for musical fruit this shield can be used to make a game controller from playdough or trigger any keyboard input from any conductive medium or surface, people, copper tape, fruit, water, even some plants, the list is endless.
This shield for Arduino gives you alligator breakouts for the 6 analogue inputs allowing you to use it just like the MakeyMakey boards. It also has LED's on each pin to indicate when an input is received.
This is a shield only and will require an Arduino such as the Uno R3 to operate.
