The Qwiic Dynamic NFC/RFID Tag graduates to reds and the AWS IoT ExpressLink SARA-R5 Starter Kit gets a new version.
The new ENS160 Air Quality Sensor is now available with two new SparkX boards!
SparkX is back with a new NFC/RFID Tag, the FLIR Lepton Breakout V2 is now available on its own, and we have a new and better way to remove a U.FL-terminated cable.
On this fine Friday, we bring you a new NFC-RFID Expansion Board for the Onion Omega, and three skinny, addressable RGBW LED strips!
Great article - thanks for presenting in such an engaging way. Many years ago I programmed in Ada - it was great to read the back story of…
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…
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…
