Join us on June 8th at 10am Mountain Time for a webinar about 10BASE-T1L Single-Pair Ethernet (SPE). SPE significantly improves your ability to acquire and transmit data quickly and reliably and represents a major leap in technology to support automation, reduce costs, and improve data transmission.
Learn all about how to use implement enterprise-grade safety systems for large-scale factories using computer vision and machine learning with this workshop - now available without registering.
SparkFun heads to Chicago this week to attend the American Library Association (ALA) Midwinter meeting.
A recap of our Let It Glow e-card crafting class and our trip to Maine teaching at Berwick Academy.

I know a guy who is a big "fan" of IoT, even though he's not all that technical. His "day job" is as a business attorney, so he can afford a…
That's true, the blue LEDs would ideally have a resistor closer to 4x than 2x when jumping from 3.3V to 5V. I don't remember my original…
Thanks for your reply! Your "roughly double" resistances for 5V vs 3.3V imply that the difference between LED drop and 3,3V is same as 3,3V…
Your right, that would be a great way to fine tune the current for LEDs! You're also correct that the goal of this project was finding the…
Hi there! For the sake of brevity, I didn't go into full detail about how exactly I calculated the 5V resistor values. But in short, I took…
Responding to your note about the highly non-linear relationship between the pot position and the current -- a way to address this would be…
Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…

That was fun to watch. Now to figure out how to ship the boards, inexpensively.
