This year, SparkFun turns 20. Take a look back with us at the last two decades and share what our top products were each year! Which ones do you have in your workshop?
A new Analog MEMs Microphone Breakout is now available as well as two new 5V Buck Regulators.
This week we take a close look at the Qwiic-enabled Tsunami Super WAV Trigger, 25 Voice version!
Our new GNSS Correction Receiver utilizing the NEO-D9S from u-blox is now available!
We are working on a lot of products behind the scenes so we are taking it a little easy with this week's Product Post!
From an automated mushroom farm to the first NFT in space! Read on to find out what happened at the Jan '22 Miami Hack Week!
Alie highlights her crazy experience co-hosting the Arm DevSummit TV show and shares her can't miss sessions from the event.
In this follow-up, I’ll show you the (mostly) finished project, talk about what I used, what I learned along the way, and just how much fun it is to have a robot that throws candy bars with unwavering accuracy and consistency.
It seems this Halloween we once again have additional considerations to take into account. I'm focusing on handing out candy to trick-or-treaters while maintaining proper social distancing.
Last month, we gave you a sneak preview of an upcoming exhibit at the Hong Kong History Museum. The creator, Alexson Chu, was using SparkFun parts and projection mapping to create an interactive learning experience for museum goers. Well, the installation premiered yesterday, and we have an inside look.
Museums are always looking for ways to engage their visitors. See how one artist is using SparkFun parts and projection mapping to make that happen.
Working from home is not without its difficulties, but with just a couple of proximity sensors and SparkFun's new Qwiic Dual Solid State Relay, you can create a light show with a wave of your hands.
Taking what I've learned about LED color mixing and Python, along with our LumiDrive LED Driver and LuMini LED Ring, I set out to create a light ring for macro photography that surpasses all others.
We use 0603 SMD packages but the electronics world uses much smaller sized components.
Wherein I take a break from pushing pixels around to wire my biker scout trooper helmet for sound.
