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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
