This tutorial will show you how setup a simple peer-to-peer connection to send and receive sensor data between two ESP32 WiFi boards.

Learn how to affix a GNSS antenna, use PPP to get its ECEF coordinates and then broadcast your own RTCM data over the internet and cellular using NTRIP to increase rover reception to 10km!

Getting GNSS RTCM correction data from a base to a rover is easy with a serial telemetry radio! We'll show you how to get your high precision RTK GNSS system setup and running.

Tell the time with this fantastic Alchitry project using clocks to make a clock!

What time is it? Time for you to... Qwiic-ly build a GPS clock and output it to a display! This project provides you with the current date and time using GPS satellites. Read the date and time as a digital or analog clock. Or even configure the clock for military, your time zone, or automatically adjust the time for daylight savings time!

We took two of our biggest robotics partnerships from the previous year and shazamed them together into one robot to rule them all!

Qwiic-ly build a digital indoor thermometer to measure the ambient temperature of the room and display it using an OLED on an I2C bus!

Learn how to record and playback controller 'macros' for your Nintendo Switch using a Raspberry Pi, SparkFun Top pHAT, and Joycontrol.

Learn how to flash firmware Over-the-Air using a BLE React WebApp and ESP32

Need a great project for your Raspberry Pi 4 kit? Use it to create a command center to display the weather, clock, your calendar, or even a news feed!

In this tutorial we'll revisit some RFID basics and practice by making a remote work logger using an RFID reader and a GPS module. You'll scan a card and get ID, location, and time. All the perfect data to punch in and punch out from the middle of Nowhere!

Monitor the weather without being exposed to it through wireless communication between two micro:bits using the radio blocks! This is useful if your weather station is installed in a location that is difficult to retrieve data from the OpenLog. We will also explore a few different ways to send and receive data.

We took two of our biggest robotics partnerships from the previous year and shazamed them together into one robot to rule them all!

Safely reboot or shutdown your Raspberry Pi to avoid corrupting the microSD card using the built-in general purpose button on the Qwiic pHAT v2.0!

A comparison of analog and digital temperature sensors. Which is better?

Did you know that most garage doors are at risk of a roll jam attack? Here we make a DIY garage door remote-control system that is much more secure than most commercial-ready products using the latest in ECC cryptography.

Want to get started in robotics? Look no further than the SparkFun autonomous kit for the Sphero RVR! Whether you purchased the Basic or Advanced kit, this tutorial will get you rolling...

This tutorial will show you how to build a magnetic levitation circuit using common parts.

The Qwiic Pro Kit was designed to allow users to get started with Arduino without the need for soldering or a breadboard. We've included three inputs (a joystick, accelerometer, and proximity sensor) and one display that can be daisy chained to the RedBoard Turbo (SAMD21) Development Board.

In this tutorial, we will build an EL wire dance suit that can be controlled by a wireless glove controller!

Protect your project by adding a fuse in your circuit to save it from molten destruction.

Let's ramp up our GPS tracking skills with KML files and Google Earth. We'll make a tracker that logs location and allows us to visualize our steps with Google Earth.

The goal of this project is to have a website hosted on an ESP32 that controls any relay controlled device connected to a local network and keeps a dynamically updated state of those devices.

In this tutorial, we will modify the 12V EL wire inverter to power the EL Sequencer/EL Escudo Dos off a single power supply.
