Asynchronous serial communication concepts: packets, signal levels, baud rates, UARTs and more!

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

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

Not working as expected? In this tutorial, we will be exploring a few general troubleshooting tips and possible solutions that frequently come up with SparkFun's Technical Support.

The SparkFun ESP8266 Thing Dev Board is a powerful development platform that lets you connect your hardware projects to the Internet. In this guide, we show you how to combine some simple components to remotely log temperature data, send yourself texts and control lights from afar.

The Qwiic Distance Sensor - VL53L1X is a time of flight sensor that is capable of several modes, as well as having a range of 4M. It's cousin VL53L4CD is also a time of flight sensor with similar characteristics but it has a range of about 1.3M. Let's hook it up and find out just how far away that thing over there is.

Find out your oxygen saturation level or check out your heart rate using the MAX30101 biometric sensor and MAX32664 Biometric Hub via I2C!

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.
