SparkFun Qwiic Button Breakout

Buttons are an easy and tactile way to interface with your project, but why deal with debouncing, polling, and wiring up pull-up resistors? The SparkFun Qwiic Button Breakout simplifies all those worries away into an easy-to-use I2C device. Utilizing our Qwiic Connect System, using the button is as simple as connecting a cable and loading pre-written code. This breakout allows you to choose which 12mm illuminated button color you want to solder onto your breakout, matching your project. If you need multiple buttons for your project, fear not! Each button has a configurable I2C address, so you can daisy-chain multiple buttons over Qwiic and still address each one individually. We've an example in our Arduino library that provides a straightforward way to configure your Qwiic Button to any desired I2C address. 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. In addition to handling blinking and debouncing, the Qwiic Button has configurable interrupts which can be configured to activate upon a button press or click. We've also taken the liberty of implementing a FIFO queue 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!
