Version 4.1 of the SparkFun Inventor's Kit for Arduino Uno is now available! We also have three new heatsink cases, and a fan SHIM for your Raspberry Pi 4.
We added a follow-up GPS tutorial to increase your GPS skills a few weeks ago. Now we want to show you a practical example with a handheld GPS coordinate logger that will pin locations for your viewing pleasure using Google Earth.
I'm using six of the same sensor in my fiber optic suit, with only four hardware configurable addresses. I need to take advantage of my ESP32 to create multiple I2C buses.
What do you do after the SparkFun Inventor's Kit for Arduino? Here are a few more tutorials to help take your projects to the next level!
What do you do after the SparkFun Inventor's Kit? The RedBoard Qwiic in your kit offers a world of opportunities – here are a few tutorials to help you dive into the Qwiic ecosystem with your SIK!
What do you do after the SparkFun Inventor's Kit? The world of electronics using Arduino is vast – here are a few tutorials to help take your projects to the next level!
USB-to-serial UART bridges like the CH340 make it easier to upload code to an Arduino and pass serial data to/from your computer. Make sure to install the respective drivers before getting started.
Learn what a logic level is, and how to interface between different technologies, with a few of our tutorials!
We shot for the moon to develop the next flagship microprocessor module that can be the mainstay for the next generation of development boards.
We have ported another "still relevant" tutorial from our archives, and added additional content to make it even more helpful on your next project!
Control a robot wirelessly with your hand using XBees, Arduino and an accelerometer.
Using EL once again for my students' performance using a glove controller, XBees, EL sequencers and Arduino.
Control your RedBot programmed with Arduino using the wireless joystick and a pair of XBees!
The Sphero RVR and its Autonomous Robotics Kits are available for pre-order, along with the NVIDIA Jetson Nano. Also, since you asked for it: Arduino Pro Mini Starter Kits!
The AST-CAN485 is back in full force with a WiFi Shield and a 24V I/O Shield! We also have three new Qwiic boards from Zio and a GNSS Multi-Band Antenna.
