Previously, in RasPipe: A Raspberry Pi Pipeline Viewer, Part 1, we explored writing a visualization of standard streams using Python and the Pygame library to render simple graphics on a PiTFT.
Next, we’ll talk about making that visualizer (or other code) available over the network, so that you can easily send it traffic from other computers, including Linux, Windows, OS X, and mobile devices.
We’ll use a grab bag of tools to accomplish this:
netcat – a command-line utility for easily pushing traffic around a network.
Node.js – a fast, capable server-side JavaScript implementation with a bunch of useful library code available.
Flask – a fast and easy Python web application framework.
By the end of this guide, you should be equipped with a useful toolkit for bridging the gaps between networked machines for all sorts of projects.
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
