Accelerometer Basics
A quick introduction to accelerometers, how they work, and why they're used.
Processor Interrupts with Arduino
What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.
AST-CAN485 Hookup Guide
The AST CAN485 is a miniature Arduino in the compact form factor of the ProMini. In addition to all the usual features it has on-board CAN and RS485 ports enabling quick and easy interfacing to a multitude of industrial devices.
Lessons in Algorithms
Learn techniques on how to use Finite Impulse Response (FIR) filters and other data-processing tools to turn data into information.
HMC6343 3-axis Compass Hookup Guide
How to hook the HMC6343 -- a high-end, tilt-compensated compass module -- up to an Arduino. Never get lost again!
Getting Started with Walabot
See through walls, track objects, monitor breathing patterns, and more using the power of radio frequency with the Walabot! In this tutorial, we will explore Walabot’s features using the Software Demo Kit (SDK) on Windows and the Application Programming Interface (API) on Linux-based distributions for embedded projects.
TFMini - Micro LiDAR Module Hookup Guide
The TFMini is a ToF (Time of Flight) LiDAR sensor capable of measuring the distance to an object as close as 30 cm and as far as 12 meters! The TFMini allows you to integrate LiDAR into applications traditionally reserved for smaller sensors such as the SHARP GP-series infrared rangefinders.
SparkFun GPS-RTK Dead Reckoning ZED-F9R Hookup Guide
The u-blox ZED-F9R is a powerful GPS-RTK unit that uses a fusion of IMU, wheel ticks, a vehicle dynamics model, correction data, and GNSS measurements to provide highly accurate and continuous position for navigation in the difficult conditions. We will quickly get you set up using the Qwiic ecosystem through Arduino and Python so that you can start reading the output!
