This is the third and final step of producing a GEMMA bracelet which can have its LED pattern programmed using an NFC capable phone. In the previous 2 stages, I talked about putting together the hardware and producing an app which would communicate with the bracelet from the phone. Now we need to tie the two ends together.   Step 1 The first step is to produce a dummy or fake input and have the GEMMA process it and play the relevant pattern on the LEDs. To do this we'll set up a new sket ...
It's been a while since I last posted - I've had a lot of work to do with uni, but now I can continue writing this project up, and I hope you enjoy reading some more on it and hopefully learning.   Last time I wrote about soldering together the hardware to create an NFC based bracelet which will glow based on a phone pattern. Today I'm going to write about creating the code on an android device which will change the bracelet's pattern. I'll be using Android Studio, which you can download ...
