Arduino

Measure relative humidity and temperature or your environment with the RHT03 (a.k.a DHT22) low cost sensor on a single wire digital interface connected to an Arduino!

This tutorial provides everything you need to know to get started with the Roshamglo badge.

Turn your Roshamglo board into a (nearly) universal TV power button.

Put together your Rotary Dial Kit and light it up with our Arduino example code!

The RP2040 is the first microcontroller from the Raspberry Pi Foundation. Updated with the new mikroBUS™ socket, the RP2040 development board expands its horizons with a growing ecosystem of +1100 drop-in Click boards™. Click to learn more.

Want to take a stab at advancing your programming skills? Check out the Thing Plus - RP2040, with the first microcontroller from the Raspberry Pi Foundation. This guide will get you started working with the RP2040 and programming in MicroPython and C/C++.

An introduction to the Atmel ATSAMD21G18 microprocessor and our Mini and Pro R3 breakout boards. Level up your Arduino-skills with the powerful ARM Cortex M0+ processor.

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

A hookup guide for the Satellite Transceiver Breakout - Swarm M138 (SPX-19236)

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.

This tutorial will show you how setup a simple peer-to-peer connection to send and receive sensor data using LoRa.

An overview of each component in the SparkFun Sensor Kit, plus links to tutorials and other resources you'll need to hook them up.

Hookup guide for the Serial Controlled Motor Driver

This tutorial will show you how to communicate with your serial devices using a variety of terminal emulator applications.

This guide contains all the information you will need to explore the 21 circuits of the SparkFun Inventor's Kit for the Arduino 101/Genuino 101 Board.

We can use the parts and concepts in the SparkFun Invetor's Kit to make a primitive keyboard instrument.

So you've built up a Simon Says kit? What next? This tutorial will get you up and running with Arduino software, guide you through a few example sketches, and send you on your way to create your own. Careful, this stuff is highly addictive. :)

This is a tutorial demonstrating one of many techniques to "hack" the Simon Says. We will highlight the technique to take your Simon Says Wireless.

A basic guide to getting started with the RFID Tag Reader breakout and how to read and write multiple RFID tags over multiple feet!

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.

Equip your Arduino project with a sliding soft potentiometer to monitor position or adding linear control to your project.

The Sound Detector is a microphone with a binary output. This guide explains how it works and how you can use it in your projects.
