In this tutorial, we will solder headers to the surface mount pads of the LS20031 GPS receiver and read the output using an Arduino!

Take your volume knob beyond 11 with the Qwiic Twist digital RGB LED encoder via I2C!

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).

How to assemble the WiFi IR Blaster and program it using Arduino. You'll be controlling IR devices from the web in no time!

How to use Arduino or CircuitPython to develop applications for the nRF52840 Cortex-M4 Bluetooth SoC.

A hardware overview and hookup guide for the SparkFun Pro nRF52840 Mini -- a breakout for Nordic's impossibly cool Bluetooth/ARM Cortex M4 SoC.

The SparkFun LTE CAT M1/NB-IoT Shield equips your Arduino or Arduino-compatible microcontroller with access to data networks across the globe. This shield adds wireless, high-bandwidth cellular functionality to your IoT project!

How to setup and use the LoRa Gateway 1-Channel in Arduino.

In this tutorial, we will connect different RGB LED matrix panels to PixelMatix's SmartLED shield and Teensy.

Learn how to wield the power of 18 channels of UV to NIR spectroscopy with AS72651 (UV), AS72652 (VIS), and AS72653 (NIR) sensors!

The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to easily integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders. With the added Qwiic feature, you can quickly connect to the sensor via I2C!

An introduction to MQTT, one of the main communication protocols used with the Internet of Things (IoT).

Using the super blazing, nay blinding, fast SAMD21 whipping clock cycles at 48MHz and the RFM96 module to connect to the Things Network (and other Radio woodles).

Learn the options for powering your LilyPad projects, LiPo battery safety and care, and how to calculate and consider power constraints on your projects.

The Melexis MLX90640 contains a 32x24 array of thermopile sensors creating, in essence, a low resolution thermal imaging camera. In this guide, we’ll go over how to connect your Qwiic Infrared Array with MLX90640 and get it communicating with Processing to produce a nice thermal image.

Find out where you are! Use this easy hook-up guide to get up and running with the SparkFun high precision GPS-RTK NEO-M8P-2 breakout board.

Hookup guide for the MAX98357A I2S audio breakout board.

In this digital fabrication project featuring 3D printing, laser cutting, and DIY electronics, you will build a beautiful design object for your desktop or night stand.

Using the ESP32 LoRa 1-CH Gateway as a gateway and device, and pushing data to The Things Network.

The Single Supply Logic Converter allows you to bi-directionally translate signals from a 5V or 3.3V microcontroller without the need for a second power supply! The board provides an output for both 5V and 3.3V to power your sensors. It is equipped with a PTH resistor footprint for the option to adjust the voltage regulator on the low side of the TXB0104 for 2.5V or 1.8V devices.

The AVR-based Qwiic Serial Enabled LCDs are a simple and cost effective solution to include in your project. These screens are based on the HD44780 controller, and include ATmega328P with an Arduino compatible bootloader. They accept control commands via Serial, SPI and I2C (via PTH headers or Qwiic connector). In this tutorial, we will show examples of a simple setup and go through each communication option.

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.

Have a bunch of sensors with the same I2C address? Put them on the Qwiic MUX (TCA9548A) to get them all talking on the same bus!
