This is a GPS controlled clock - a clock you truly never have to set! Using GPS and some formulas, we figure out what day of the week and if we are in or out of daylight savings time.

Learn the differences between AC and DC, the history, different ways to generate AC and DC, and examples of applications.

We admit the Arduino IDE isn't for everyone. Here are some other options for programming your Arduino boards, including web interfaces and graphical programming languages.

Get started with sound monitoring using the SparkFun analog MEMS microphone breakout board with Arduino!

Get started with the SparkFun analog MEMS microphone breakout board! In this tutorial, we will be connecting the differential MEMS microphone to an Arduino using the WM8960 audio codec.

The world is analog. Use analog to digital conversion to help digital devices interpret the world.

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

Connect, power, and control your APA102 addressable LED strip!

The APDS-9301 sensor is an I2C connected luminosity sensor which returns measurements in lux.

Getting started guide for the Avago APDS-9960 color, proximity, and gesture sensor.

An update to our classic Arduino Shields Tutorial! All things Arduino shields. What they are and how to assemble them.

Read humidity, pressure and luminosity quickly and easily. Add wind speed, direction and rain gauge for full weather station capabilities.

How to communicate between an Electric Imp and Arduino using serial.

Learn how to assemble and drive DC motors using the v2.0 Ardumoto Shield.

Use an Electric Imp and accelerometer to create an "Are You OK" widget. A cozy piece of technology your friend or loved one can nudge to let you know they're OK from half-a-world away.

A guide describing the ARGOS satellite network - as used by our ARTIC R2 satellite communication products

A hookup guide for the ARGOS Satellite Transceiver Shield - ARTIC R2 (SPX-17236)

How to program SAMD21 or SAMD51 boards (or other ARM processors).

With the latest Artemis DK, board, we now offer full Bluetooth support within the Arduino IDE and development with Mbed™ OS. While we have worked tirelessly to get the Artemis module supported in the next Mbed™ OS release, the next release isn't slated until after the Artemis DK becomes available to the public. Therefore, this post will provide users with a jump start for developing with Mbed™ Studio, prior to the next release (in a beta of sorts), by utilizing our fork of Mbed™ OS.

Get our powerful Artemis based boards (Artemis Nano, BlackBoard Artemis, and BlackBoard Artemis ATP) blinking in less than 5 minutes using the SparkFun Artemis Arduino Core!

This is an in-depth guide on developing in the Arduino IDE for the Artemis module and any Artemis microcontroller development board. Inside, users will find setup instructions and simple examples from blinking an LED and taking ADC measurements; to more complex features like BLE and I2C.

The SparkFun Artemis Global Tracker combines the Artemis processor with an Iridium 9603N satellite transceiver, ZOE-M8Q GNSS transceiver, and MS8607 PHT sensor. With a clear view of the sky, this board allows you to send and receive short data messages from anywhere in the world including remote locations far beyond the reach of WiFi and GSM networks. Follow this guide to get started with the Artemis Global Tracker.

It's now easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS726X spectral sensors allow you to detect wavelengths in the visible range (VIS) and near infrared range (NIR)!
