If you're ready to step up your Arduino game from older 8-bit/16MHz microcontrollers, the RedBoard Turbo is an awesome alternative.

Detect human movement THROUGH WALLS using WiFi!

SERCOM (Serial Communication) is a multiplexed serial configuration used on the SAMD21, SAMD51 and other boards. It allows you to select various serial functions for most of your pins.

In this post, I will show how I made a static web server using Docker and Docker Compose.

The SparkFun Qwiic Joystick combines the convenience of the Qwiic connection system and an analog joystick that feels reminiscent of the thumbstick from a PlayStation 2 controller.

The Qwiic Proximity Sensor is a simple IR presence and ambient light sensor utilizing the VCNL4040. This sensor is excellent for detecting if something has appeared in front of the sensor; detecting objects qualitatively up to 20cm away.

The Qwiic RFID ID-XXLA is an I2C solution that pairs with the ID-LA modules: ID-3LA, the ID-12LA, or the ID-20LA, and utilizes 125kHz RFID chips. Using the product's interrupt pin, we'll discuss how to get, store, and compare unique RFID IDs.

This article covers everything I used to build the code pipeline for the website!

This post will go over the creation of a VM, setup, and all the needed software for a development environment that can theoretically run offline.

Set up trigger phrases to carry out specified actions on your Raspberry Pi.

The SparkFun ZOE-M8Q and SAM-M8Q are simple GNSS receivers with different antenna configurations. They both have a 2.5m horizontal accuracy!

If you think back to your electronics I (or maybe II) class, you'll remember one of the really important properties of a voltage amplifier is that it barely loads your input—that is to say, it has an infinite input impedance.
