Use the MicroMod Input and Display Carrier Board, paired with a ESP32 Processor Board, to stay on top of your meetings and email.
For this year's Open Source Hardware Association Summit, there was no venue. Instead, it was a completely virtual affair, allowing all of us to hear a host of amazing speakers from the comfort of our own homes.
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.

Sometimes you need the real-time interaction that only a meeting can provide. Keep family members from wandering in on your important meetings with this simple alert!
Robotics, garage doors, computers and more. Have more fun working at home with these DIY projects!
Like most of us here at SparkFun, many of you are navigating working from home. Here's a snapshot of how it's going from our perspective.

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…

Nice initiative Dryw! But there's something a bit off in the "5V resistor value" calculations, supposedly using Ohm's law. The forward…
