It's a known trick that we can use LEDs in reverse. We'll explore how to use them as photodetectors with Arduino and create a simple demo that responds to hand swipes.
Here's how you can use boards with your Chromebooks in makerspaces, libraries and schools
How to make your own seismometer to measure ground activity, such as earthquakes and volcanic eruptions.
Our biggest sale on Arduino is happening all weekend, and we have new products as well!
Just in time for Arduino Day, we're bringing you the magic of infographics.
Deals so good you'll think we're joking, but we're not.
Reagan talks about making the CubeRinth Maximus for Two Bit Circus.

How and why we made them
An approach to timing Arduino sketches.
SparkFun's drivers for MS Windows are now signed!
SparkFun: helping people throw stuff into space since 2003
This post highlights my method of creating the control system for our AVC battle arena.
Ever wonder how the Arduino IDE translates your code into instructions for the processor?
Earlier today, Arduino announced a new partnership with Microsoft and special support for Windows.
A look at implementing the Arduino blink.ino sketch as an explicit state machine. To further explore state machines, an alarm clock state diagram is drawn and implemented.
We want to update our customers on where we stand with the on-going Arduino saga.
Celebrate Arduino Day with these great deals!
This coming Saturday, March 28th, is Arduino Day - celebrate with us!
The release of Arduino 1.6 has really improved my Arduino-programming life thanks to custom platform support, command line utilities and line numbers!
You need to reflash the firmware - see: https://github.com/sparkfun/SparkFun_DataLogger/issues/3 Once you flash using that command, you can…
I think I just overwrite the DataLogger IoT firmware was doing firmware update and accidently hit Arduino script file, instead of cool term…
Thanks for the great description! I hadn't even been aware of the existance of NNSS, though in the mid 1980s, I'd looked at LORAN-C for a…
Thanks for the L band sharing !
Over the years, I've been pretty vocal about wanting on-board RTCs, with at least the possibility of connecting something like a coin…
Not only does VBAT supply the RTC, but there’s also battery-backed RAM onboard too! With the amount of space available on the Thing Plus…
Interesting... it sort of covers one of my "hot buttons", that is having an RTC. In looking at the schematic, I noticed that the "BAT"…
But Social Engineer's LOVE him. Good job catching so many of the buttons social manipulators use, but I nearly thought Sparkfun was off…
There's a disclaimer at the very end, hopefully that's enough to keep people from attempting. Glad you liked it!
Wow great blog!
