Macros allow toggling of debug logs, platform features, and memory optimizations. They also provide cleaner logs with automatic line numbers and function names.

Not all random values are equal. Explore the difference between pseudo-random generators and true hardware randomness in embedded projects.

The SparkFun Environmental Sensor - BME680 (Qwiic) is a breakout for the 4-in-1 BME680 gas sensor from Bosch. The BME680 combines a gas sensor with temperature, humidity and barometric pressure sensing for a complete environmental sensor in a single package.

Experiment 10 from the Inventors Kit for Raspberry Pi Pico, in which we controlling ZIP LEDs with code.

In this episode, we’ll go one step further by creating and using custom interfaces in both Python and C++. You’ll learn how to define your own message and service types and use them in publisher/subscriber and client/server architectures.

Clear overview of HSTX architecture—async FIFO, command expander, output shifters—and where it fits in maker projects.

When you first buy an Alchitry Au+, Alchitry Au, or Alchitry Cu board, the default FPGA configuration creates a fancy wave effect on the LEDs. In this tutorial we are going to walk through different steps for how to make something like this.

Learn how CoreXY uses crossed belts and two motors to move payloads with speed, precision, and reduced mass compared to Cartesian systems.

Experiment 9 from the Inventors Kit for Raspberry Pi Pico, in which we explore a capacitor charging circuit.

In this tutorial, we will see how services work by creating a custom server and client in C++ ROS nodes.

Use a laptop webcam, OpenCV, YOLOv8, and MQTT to detect objects in real time and publish events to the cloud. Code and setup included.

Learn essential skills for interpreting electronic component documentation. Explore pin configurations, operating conditions, truth tables, and timing diagrams.
