Qwiic Button Breakout
£3.33 ex VAT
Buttons 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 SparkFun Qwiic Button Breakout simplifies all of those nasty worries away into an easy to use I2C device! Utilizing the Qwiic Connect System, using the button is as simple as connecting a cable and loading up some pre-written code! This breakout allows you to choose which colour 12mm illuminated button you want to solder onto your breakout to match 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. You can download the Arduino library through the Arduino library manager by searching 'SparkFun Qwiic Button' that will provide a super-easy way to configure your Qwiic Button to whatever I2C address you desire.
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. They'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!
