Have you ever wanted to make a secure IoT system? Then get started with this tutorial, to learn how to use some of the standard features of the SparkFun Cryptographic Co-processor! We will provide an introduction to cryptographic authentication, and then walk through the examples provided in the Arduino library. By the end, you will be able to create and verify digital signatures, use time-to-live tokens (aka NONCE), and have the tools and skills to add a very high level of authentication to all of your communication channels.

Measure temperature, humidity, barometric pressure with the SparkFun Atmospheric Sensor Breakout BME280 (Qwiic).

The SparkFun Inventor's Kit (SIK) Experiment Guide contains all of the information needed to build all five projects, encompassing 16 circuits, in the latest version of the kit, v4.1.

This hookup guide will get you started with connecting and using the Pi Servo pHAT on a Raspberry Pi.

Let's chat about layout and design considerations when using the Artemis module.

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 tutorial covers the basic functionality of the SAMD51 Thing Plus and highlights the features of the new ARM Cortex-M4F development board.

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

Need to add more analog inputs for your project? Check out the Qwiic 12-bit ADC.

If you are tired of taking up GPIO pins, wiring a bunch of pull up resistors, and using firmware that scans the keys taking up valuable processing time... check out the new Qwiic Keypad.

Learn how to develop code blocks for the Micro:bit in Microsoft MakeCode!

This is a tutorial to go in-depth about the SparkFun HyperDisplay Arduino Library.

How to setup extra SPI, UART, and I2C serial ports on a SAMD-based boards.

An introduction to the RedBoard Turbo. Level up your Arduino-skills with the powerful SAMD21 ARM Cortex M0+ processor!

This tutorial covers the basic functionality of the RedBoard Qwiic. This tutorial also covers how to get started blinking an LED and using the Qwiic system.

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.

How to eschew the Arduino IDE for a combination of and Arduino command-line tool (Arduino CLI) and a professional code editor (Visual Studio Code).

Take your nRF52840 development to the next level -- build your applications with the nRF5 C SDK. This tutorial explains how to set up a development environment based around the GNU Arm Embedded Toolchain.

MicroPython is an implementation and subset of the Python 3 programming language that can be used on microcontrollers. This guide will walk you through writing MicroPython programs for the ESP32 Thing development board.

In this tutorial, we look at various methods for running a script or program automatically whenever your Raspberry Pi (or other Linux computer) boots up.

Tkinter is the standard graphical user interface package that comes with Python. This tutorial will show you how to create basic windowed applications as well as complete full-screen dashboard examples complete with live graph updates from matplotlib.

In this tutorial, we will use a Raspberry Pi 3 and the Pi AVR Programmer HAT to program an ATMega328P target. We are going to first program the Arduino bootloader over SPI, and then upload an Arduino sketch over a USB serial COM port.

Use matplotlib to create a real-time plot of temperature data collected from a TMP102 sensor connected to a Raspberry Pi.

This guide will show you how to write programs on your Raspberry Pi using Python to control hardware.
