When plugged into a computer’s USB port, phatIO (pronounced “fat-eye-oh”) appears as a USB filesystem/memory stick. You can control devices connected to phatIO by writing to files on that filesystem. Any computer that can write to a USB memory stick and any program/language that can write to a file can talk to phatIO and control things.
phatIO significantly reduces the effort needed to control things with a computer – no drivers have to be installed or low level libraries used. Each of the 20 general purpose IO pins can be controlled by saving a “0” or “1” to their control file.
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.
