This tutorial will take your SparkFun Qwiic Ultrasonic Distance Sensor to the next level by turning it into a parking distance sensor!

How to use and re-program the OpenLog Artemis, an open source datalogger. The OLA comes preprogrammed to automatically log data. The OLA can also record serial data, analog voltages, or readings from external Qwiic-enabled I2C devices. Some of these Qwiic-enabled devices include GPS/GNSS modules, pressure, altitude, humidity, temperature, air quality, environment, distance, and weight sensors.

The essential parts for beginning (or even experienced) hobbyists that gives you all of the basic through-hole components you will need to get started playing with embedded projects. We'll identify a few parts in the kit and provide a few basic circuits to get started!

The SparkFun STC31 CO2 Sensor can accurately measure CO2 concentrations up to 100% with high repeatability and long-term stability, thanks to humidity and temperature compensation provided by the built-in SHTC3. This tutorial will show you how!

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, v4.1.2 and v4.1.

Power up your 5V I2C devices on the Qwiic system! This tutorial shows you how to use the SparkFun Qwiic 5V Boost to integrate power-hungry sensors like the SEN55 seamlessly.

The MyoWare® 2.0 Muscle Sensor, an Arduino-compatible, all-in-one electromyography (EMG) sensor from Advancer Technologies. In this tutorial, we will go over the features and related shields to connect the sensor to a muscle group.

How to interface with the INA169 Breakout Board to measure current.

The u-blox ZED-F9R is a powerful GPS-RTK unit that uses a fusion of IMU, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements to provide highly accurate and continuous position for navigation in the difficult conditions. We will quickly get you set up using the Qwiic ecosystem through Arduino and Python so that you can start reading the output!

Review, teardown, and hacking tutorial for the MindWave Mobile, a $99 commercial grade EEG sensor.

This guide takes you through the basics of building 11 different circuits with the SparkFun Tinker Kit and how to program them using the Arduino IDE.

In this tutorial, we will cover how to calibrate your Qwiic Optical Tracking Odometry Sensor (or "OTOS") with Arduino and Python Examples.

Sometimes we want to do more with our data than just watch the values roll by on a screen. In this tutorial, we'll take a look at one way we can translate that data to movement.

This tutorial will take your SparkFun Qwiic Ultrasonic Distance Sensor to the next level by adding a cool little OLED display.

In this tutorial, we will slowly turn on the load and then slowly turn it off using the N-channel MOSFET.

In our previous Bluetooth tutorial called Sending Sensor Data Via Bluetooth, we showed how to display data from a triple axis accelerometer over the Arduino IDE’s serial monitor. Continuing off of the first tutorial, we are going to expand this project to include more capabilities for visualizing and interacting with your accelerometer data.

In this tutorial, we will show you how to get started on incorporating Bluetooth into your electronics projects. This project uses a SparkFun Thing Plus ESP32 Wroom USB-C to display data from a Triple Axis Accelerometer over Bluetooth.
