We've been using Johnny-Five for the majority of this book, but we haven't really touched on one of its best features! While the REPL and the API are definitely strong points, what really stands out about it is its wide array of supported microcontrollers.

To be up to date with what Johnny-Five supports, check out johnny-five.io/platform-support—this page, as we saw in the earlier chapters, contains all the platforms that Johnny-Five supports, and also what types of component they support.

Wrappers, which we'll use in this build, are pieces of code that translate Johnny-Five's Firmata method of communicating to other platforms that don't necessarily use Firmata. In our build, for instance, we'll be using a Particle Photon, which uses a firmware called VoodooSpark. The particle-io wrapper essentially teaches Johnny-Five how to speak VoodooSpark, so we can use the Photon with our existing code.

Let's check out how easy it is to move code by moving...
