Just a quick update to ket you all know this project is being shelved for the moment while i work on some other projects.

I shall be using some of the components in another project for the time being and will be re-ordering parts when I return to this one.

I have the code pretty much finished for this one (sketches for the master and slave arduinos) as well as more detailed plans of the build; these will be shared with you very soon.

If anyone would like to take this project on further with my material please let me know and I will happily invite you to collaborate.

Cheers!
