SchematicProduct Overview
Buttons are an easy, tactile way to interact with your project, but why deal with debouncing, polling, and wiring up pull-up resistors? The Qwiic Button, with a built-in red LED, 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.
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 have 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 that 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, which 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 button's status, but instead can run a small function whenever the button is pressed or clicked!
