This is the \u003cstrong\u003eClassic\u003c\/strong\u003e version of\u003cstrong\u003e Circuit Playground\u003c\/strong\u003e, which comes with an ATmega32u4. It's designed to be used with \u003cstrong\u003eArduino IDE\u003c\/strong\u003e and \u003cstrong\u003ecode.org\u003c\/strong\u003e CS Discoveries only. It even comes with Firmata already programmed in, so you can use it immediately with code.org Discoveries without any preparation or updates. If you would like to use MakeCode or CircuitPython, check out Circuit Playground Express, which can be used with \u003cstrong\u003eMakeCode, CircuitPython \u003c\/strong\u003eor \u003cstrong\u003eArduino\u003c\/strong\u003e. Circuit Playground features an ATmega32u4 processor, just like our popular Flora. The board's also round and has alligator-clip pads around it so you don't have to solder or sew to make it work. You can power it from USB, a AAA battery pack, or with a Lipoly battery (for advanced users). Just program your code into the board then take it on the go!\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eATmega32u4 Processor, running at 3.3V and 8MHz\u003c\/li\u003e\n\u003cli\u003eMicroUSB port for programming and debugging with Arduino IDE\u003c\/li\u003e\n\u003cli\u003eUSB port can act like serial port, keyboard, mouse, joystick or MIDI\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCircuit Playground has built-in USB support. Built in USB means you plug it in to program it and it just shows up.  All you really need is a Micro-B data\/sync USB cable - not included! With the new 1.6.4+ Arduino IDE, it takes only a few seconds to add support. The Circuit Playground has USB HID support, so it can act like a mouse or keyboard and attach directly to computers. \u003cstrong\u003eHere's some of the great goodies baked in:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e10 x mini NeoPixels, each one can display any color\u003c\/li\u003e\n\u003cli\u003e1 x Motion sensor (LIS3DH triple-axis accelerometer with tap detection, free-fall detection)\u003c\/li\u003e\n\u003cli\u003e1 x Temperature sensor (thermistor)\u003c\/li\u003e\n\u003cli\u003e1 x Light sensor (phototransistor)\u003c\/li\u003e\n\u003cli\u003e1 x Sound sensor (MEMS microphone)\u003c\/li\u003e\n\u003cli\u003e1 x Mini speaker (magnetic buzzer)\u003c\/li\u003e\n\u003cli\u003e2 x Push buttons, left and right\u003c\/li\u003e\n\u003cli\u003e1 x Slide switch\u003c\/li\u003e\n\u003cli\u003e8 x alligator-clip friendly input\/output pins Includes I2C, UART, and 4 pins that can do analog inputs\/PWM output\u003c\/li\u003e\n\u003cli\u003eAll 8 pads can act as capacitive touch inputs\u003c\/li\u003e\n\u003cli\u003eGreen \"ON\" LED so you know its powered\u003c\/li\u003e\n\u003cli\u003eRed \"#13\" LED for basic blinking\u003c\/li\u003e\n\u003cli\u003eReset button\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCheck out our detailed tutorial for pinouts, driver installation, Arduino IDE, and more!\u003c\/li\u003e\n\u003cli\u003eOuter Diameter: ~50.6mm \/ ~2.0\"\u003c\/li\u003e\n\u003cli\u003eWeight: 8.5g\u003c\/li\u003e\n\u003cli\u003eSchematic, Datasheets, EagleCAD PCB files, and Fritzing are available in the product tutorial\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":50068058079465,"sku":"000023","price":35.99,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/8006\/3209\/files\/acf96b3f-CircPlayClassis.jpg?v=1769271461","url":"https:\/\/www.tinkertailor.ca\/products\/adafruit-circuit-playground-classic","provider":"Tinker Tailor","version":"1.0","type":"link"}
