In this example we will stream the data from the connected web-camera or any other camera-like device and perform real-time image processing

How can I take a photo in WL?

An onboard ADC (analog-to-digital converter) is one of the basic features of Arduino-compatible boards. With just a few lines of code, the can turn voltages into numerical values. When streamed over a serial interface, these values let the Arduino act as a live external sensor—capturing data from photodiodes, microphones, or other circuits.

In this example, we build a robust workflow for acquiring ADC samples via UART/USB and processing them in the Wolfram Language. Instead of relying on naïve streaming (which is prone to corruption), we design a lightweight framing protocol that improves integrity of data packets. Once in Wolfram Language, the values can be visualized, filtered, or transformed in real time—turning an entry-level Arduino into a toy-like oscilloscope or spectrum analyzer.

Using the power of Newton's equations and numerics to solve dynamics of arbitary planar meshes in real-time

An Ultimate Guide for non-WLJS or non-WL users

The idea of programmatically generating slides and graphics for presentations, reports, or lecture notes is far from new. Today, you can do this using Python, HTML, JSX, Julia, and more. Most of these tools follow a similar concept—combining declarative markup like Markdown and HTML. We’ll follow a similar path but add support for dynamic elements, reusable components, and event bindings. Sounds complicated? Actually, the goal is to simplify.

⚠️ Heads-up: This approach involves traditional text-based programming.

⚠️ Warning: Lots of images ahead. It is about presentations 😄
