Work’s been quite busy lately, with several things going on at once, and few things completed. Many pieces of what I am doing are scattered over the web, on my gitHub account, my various class sites, etc. Since I’m expecting students to keep a blog in my classes, I thought it might be useful to revive my own blogs as a place to keep track of some of the projects I’m in the midst of. <\/p>\n\n\n\n
I’ve been having a good time making examples<\/a> using the Message Queueing Telemetry Transfer (MQTT) <\/a>protocol lately. MQTT is a lightweight networking protocol used in many industrial networking (read: internet of things) applications. There are a number of good libraries out there for it on a variety of platforms, and a couple of useful public brokers (read: servers) that you can test your apps with, like shiftr.io<\/a> and mosquitto.org<\/a>. I like Shiftr because of the fancy motion graphic (okay, call me shallow). I’ve got examples for Arduino using the ArduinoMqttClient<\/a> library and p5.js<\/a> using the Eclipse PAHO library<\/a>. I just added one using p5.serialport<\/a> as well, so you can connect Arduino projects to each other through p5.serialport -> p5.js -> MQTT. <\/p>\n","protected":false},"excerpt":{"rendered":" Work’s been quite busy lately, with several things going on at once, and few things completed.
