This is not a full project, but rather a follow-up, an add-on to a previous guide.
Our goal is to show how our smartphone app can remote-control even the tiniest of microcontroller projects. To do that, we’ll build upon our popular Kaleodoscope Eyes NeoPixel goggles project, adding the Bluefruit LE UART Friend board to the mix. Change colors to suit your mood…from your smartphone!
To be frank, this is not a very practical extension…there’s very little code space left on the Trinket microcontroller for additional modes…but it demonstrates the core idea that adding basic Bluetooth controls no longer requires the most advanced microcontroller or lots of code. Our Bluefruit LE UART Friend and accompanying free Bluefruit LE Connect app for iOS and Android make it easy! If size and cost are at a premium, Trinket is at least an option…and it only gets better with Pro Trinket on up.
If you’ve not built the basic NeoPixel goggles, see the Kaleidoscope Eyes guide for some background.
