{"product_id":"sparkfun-qwiic-button-green-led","title":"SparkFun Qwiic Button - Green LED","description":"\u003cp\u003eButtons are an easy and tactile way to interface with your project, but why would you want to deal with debouncing, polling, and wiring up pull-up resistors? The Qwiic Button with built-in green LED simplifies all of those nasty worries away into an easy to use I\u003csup\u003e2\u003c\/sup\u003eC device!\u003c\/p\u003e\n\u003cp\u003eUtilizing the Qwiic Connect System, using the button is as simple as connecting a cable and loading up some pre-written code!\u003c\/p\u003e\n\u003cp\u003eIf you need multiple buttons for your project, fear not! Each button has a configurable I\u003csup\u003e2\u003c\/sup\u003eC address, so you can daisy-chain multiple buttons over Qwiic and still address each one individually. There's even an example in the \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_Button_Arduino_Library\" target=\"_blank\"\u003eArduino library\u003c\/a\u003e that provides a super-easy way to configure your Qwiic Button to whatever I\u003csup\u003e2\u003c\/sup\u003eC address you desire. You can download the library through the Arduino library manager by searching 'SparkFun Qwiic Button' or you can get the GitHub repo as a .zip file and install the library from there.\u003c\/p\u003e\n\u003cp\u003eIn addition to handling blinking and debouncing, the Qwiic Button has configurable interrupts that can be configured to activate upon a button press or click. SparkFun have also taken the liberty of implementing a \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Queue_(abstract_data_type)\" target=\"_blank\"\u003eFIFO queue\u003c\/a\u003e onboard the Qwiic Button where it keeps an internal record of when the button was pressed. This means that code on your microcontroller need not waste valuable processing time checking the status of the button but instead can run a small function whenever the button is pressed or clicked!

All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-qwiic-button-hookup-guide\"\u003eGet started with the SparkFun Qwiic Button Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e12mm Green LED Button rated for 50mA\u003c\/li\u003e\n\u003cli\u003eBuilt in LED can be configured for your desired level of blinkiness!\u003c\/li\u003e\n\u003cli\u003eEach button has a configurable I\u003csup\u003e2\u003c\/sup\u003eC address\u003c\/li\u003e\n\u003cli\u003eConfigurable interrupts - \u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/processor-interrupts-with-arduino\/all\" target=\"_blank\"\u003echeck out the guide here\u003c\/a\u003e!\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Queue_(abstract_data_type)\" target=\"_blank\"\u003eFIFO queue\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/8\/b\/a\/2\/f\/Qwiic_Button.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/f\/7\/1\/8\/8\/Qwiic_Button.zip\" target=\"_blank\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/learn_tutorials\/1\/1\/0\/8\/SparkFun_Qwiic_Button_Board_Dimensions.png\" target=\"_blank\"\u003eBoard Dimensions\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-qwiic-button-hookup-guide\" target=\"_blank\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_Qwiic_Button_Arduino_Library\" target=\"_blank\"\u003eArduino Library\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/learn_tutorials\/1\/1\/0\/8\/Qwiic_Button_I2C_Register_Map.pdf\" target=\"_blank\"\u003eRegister Map\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/Qwiic_Button\" target=\"_blank\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":32000924647507,"sku":"BOB-16842","price":5.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/16842-SparkFun_Qwiic_Button_-_Green_LED-01.jpg?v=1595003463","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-qwiic-button-green-led","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
