This is an exercise in how to make a problem far harder than it needs to be. Grab a magnetometer, a device which measures the magnetic fields at a point and attach it to an arduino with some LED’s.
Time to get back into some embedded systems stuff. We’re going to be working on setting up an Arduino Uno and a 144 LED neopixel light strip.
Data Cube is back! The Internet of Things coolest way to visualize interactive data. Data Cube is an IoT device that allows interactions from other places (YouTube Views, Twitter Tweets or simple Website Views) to be visualized as data traveling along an LED strip.
We’re going to start looking into communicating over serial ports with our arduino now. The final goal here is to be able to send information about what to draw over a serial connection from our web server down to the arduino.
Introducing Data Cube, the spiritual successor to Data Sphere. A data visualization project. Data Cube is going to use an Arduino and four meters of LED’s to create a 3D visualization of online social interactions.
