This guide turns a TFT Gizmo into a conversation heart, just like those chalky candies that show up around Valentines. The code is written in CircuitPython and can run on the Circuit Playground Bluefruit. If you bought an AdaBox014, then you have everything you need. Or you can get the items from the links below.
Two versions of the code are provided. The first is a simple one that will let you set predefined messages and colors and then cycle through them by pressing the buttons on the Circuit Playground. The second one uses the Bluetooth Low Energy (BLE) feature of the Circuit Playground Bluefruit along with the Adafruit Bluefruit LE Connect app to allow you to set message and colors from your BLE enabled smart phone or tablet.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
