Wemos Mini and various shields ebook

As you may know looking at this web site we are big fans of the Wemos mini and the various shields that you can buy for this hardware. We have decided to write an ebook and publish it on the Kindle store and of course any money recieved through commision will go towards buying new modules, sensors and shields. We also want to design our own shields which this would help fund.

There will be descriptions of each chapter, code examples (which is available via a github link in the book) and expected output. Here are the contents of the ebook so you can see what we have added
