When creating a proof of concept model, simplicity is usually the modus operandi. However, when you get an idea for a project requiring a POC, and at the same time you’re also hit by the holiday spirit, why not let yourself be guided by both?
Learn how to make a wireless timing device using ESP32 wireless communication.
Meet our newest Creative Technologist Mariah and learn all about what brought her here to SparkFun!
We are testing out how much soldering really changes air quality using the MicroMod Ethernet Function board and the MicroMod Environmental Function board!
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!
What's a good rave without some flashy LEDs? Read on to find out how I made these!
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.
Save time on your next project by using Flowcode to help with coding.
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…
Minor issue: "Today's Deals" is still showing SparkFun Level Shifting microSD Breakout and…
That was fun to watch. Now to figure out how to ship the boards, inexpensively.
The story goes that George Antheil was madly in love with Hedy Lamarr and this was an attempt to gain her interest. There are no documents…
