Learn about Ohm's Law, one of the most fundamental equations in all electrical engineering.

This tutorial will explain how to use and convert between the standard metric prefixes.

This tutorial covers the concept of analog and digital signals, as they relate to electronics.

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

Learn how to use the SparkFun Touch Potentiometer to control lighting, volume or other inputs in your daily life.

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.

Get started passively monitoring motion using the Panasonic EKMC and EKMB sensors with the SparkFun Qwiic PIR.

Get started with the SGP40, BME280, VCNL4040, and microOLED via I2C using the Qwiic system and Python on a Raspberry Pi! Measure VOC Index, light, temperature, humidity, and pressure from the environment. Then display them on the microOLED, serial terminal, or the cloud with Cayenne!
