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.

The LilyPad USB Plus is a sewable microcontroller that you can use with Arduino.

An overview of the updates made in the redesign of the LilyPad Development Board to the LilyPad ProtoSnap Plus and how to adapt code written for the old board to the new one.

Add sound effects to your project, prop or costume with Papa Soundie Audio Player.

This tutorial goes over the how to assemble the Chibitronics' Chibi Chip programmable microcontroller with the Chibi Clip to add more functionality to your paper circuits! Start programming your Chibi Chip by writing code (block-based and text-based) in a browser-based code editor and then transmit code through sound to your board!

This tutorial will show you how to use a headless Raspberry Pi to flash hex files onto AVR microcontrollers as a stand-alone programmer. It also tells the story about production programming challenges, how SparkFun came to this solution, and all the lessons learned along the way.

How to hook up the LilyPad Temperature Sensor as well as some project ideas and example code.
