LED Gumball Machine

An introduction to polarity in electronic components. Discover what polarity is, which parts have it, and how to identify it.

Experiments guide for the LogicBlocks kit. Build oscillators, latches, multiplexers and more with the LogicBlocks.

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.

Discussing what thermal resistance is, how it’s used for thermal management, and how to maximize the life of your project.

A top hat decked out with LED strips makes for a heck of a wedding gift.

The RFD77402 uses an infrared VCSEL (Vertical Cavity Surface Emitting Laser) TOF (Time of Flight) module capable of millimeter precision distance readings up to 2 meters. It’s also part of SparkFun’s Qwiic system, so you won’t have to do any soldering to figure out how far away things are.

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to easily integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders. With the added Qwiic feature, you can quickly connect to the sensor via I2C!

The SparkFun Arduino UNO R4 WiFi Qwiic Kit is a great way to get started with Arduino and the Qwiic-connect system - use this guide to get started!
