A few weeks ago I shared some research on absolute positioning without GPS. Since then I’ve continued digging into the subject, found a few more sources, and tried a few more things.
Recently we introduced four new PIR boards that use Panasonic’s new EKM-series PIR sensor, and I was excited to put one of them into a build.
The MicroMod RP2040 Processor is now shipping! With it, we also have the new version of the Arduino Engineering Kit and the new SenseHAT for Raspberry Pi.
Nothing says "I love you" on Valentine's Day like a homemade gift. And if that gift happens to be made using 3D-printed parts, addressable LEDs and a phone app you create yourself - everybody wins!
My friend's young son's latest obsession became my latest project, with a salvaged stepper motor, a couple of servos, and a bit of ingenuity.
The great thing about open source software is that when you want a new feature, you can just add it!
Just because it’s already October and you haven’t started this year’s Halloween build doesn’t mean it can’t still be epic! SparkFun’s Qwiic I2C environment can help even us Olympic-level procrastinators rival the street’s best Halloween builds!
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.
The added functionality of BLE in the Artemis Development Kit means it can be connected to a local web application! We explore this by streaming the on-board sensor data to a local host.
Let's go over when something like an Arduino or Teensy is more appropriate than using a Raspberry Pi.
Marcus demonstrates how the Qwiic System makes it super easy to build a novelty sound maker with a capacitive touch interface.
In a previous blog post we showed off a custom macro keyboard. In this week's post, we update it to make it wireless!
In a new tutorial we'll revisit some RFID basics, and practice by making a remote work logger using an RFID reader and a GPS module.
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!
Comparing analog and digital temperature sensors TMP36, TMP102 and TMP117. Which is better?
Here's a brief rundown and a couple of examples to help get you thinking about how you might incorporate movement into your next project using servos.
