Processor Interrupts with Arduino
What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.
Lessons in Algorithms
Learn techniques on how to use Finite Impulse Response (FIR) filters and other data-processing tools to turn data into information.
Basic LED Animations for Beginners (Arduino)
Let's have some fun with LEDs! We'll explore LEDs once again with the SparkFun RedBoard Qwiic, making cool effects, and putting those effects to work using a sensor.
Wake-on-Shake Hookup Guide
A basic hookup guide for getting started with the SparkFun Wake-on-Shake. The board gives you the ability to put your project into hibernation until bumped or shaken awake using the ADXL362 accelerometer. This means you can design projects meant to stay inert for long periods of time, possibly even several years, depending on the battery type used to power the project.
Interactive LED Music Visualizer
Use an Arduino and the SparkFun Sound Detector to create visualizations on Addressable RGB LED strips.
