Adafruit_BusIO-ification for prettier, easier-to-maintain Arduino libraries
Ever since we’ve started writing/porting CircuitPython drivers for sensors and displays and such, we’ve fallen in love with `busio` – our generalized I2C and SPI API which takes out the repetitive parts of writing drivers: i2c address scanning, writing registers, reading chunks of data and concatenating it, dealing with repeated-start chips. After doing a bunch of drivers, we started looking at our Arduino libraries with an itchy nose. Sure they worked, but they’d been building up a decade of cruft and low-level interfacing.
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.
