In the many years that Johnny-Five has been an active project, there have been myriad requests for hardware peripheral and component device support. Implementing support almost always requires the acquisition of the actual peripheral or component device, in order to adequately develop and test the driver code; most commonly, this involves visiting SparkFun, Adafruit, Amazon, or Digi-Key, and then ordering the necessary "thing". Once in hand, the author sets their own schedule for designing, developing and testing an implementation. Johnny-Five contributors and maintainers will communicate all of these "phases", as they occur, by commenting on the original support request. Eventually, either support will land or it won't (in the past, there was no support for UART devices, this is no longer the case). There are rare cases, including one which we will discuss today, where i
