Purchasing the PicoBoard
The PicoBoard is an add-on piece of hardware that has sensors to detect the amount of light, sound, and resistance. There is also a slider controller and a button. Today, the PicoBoard is manufactured and sold by SparkFun (https://www.sparkfun.com/products/10311), but previous versions of the board were sold by PicoCricket.
