I'm doing a project using the ADXL335 accelerometer from SparkFun. The actual project I'm using P5 and it's working great. I'm running workshops in parallel and want to demo the chip in real-time but am currently out of time to build something from scratch. I'm desperate for a simple processing (or something else) sketch that takes my x, y, z values being printed to the serial port from Arduino and visualizes them in some way. Can anyone point me to anything that won't need a lot of coding time and effort just now?

Thank you! Claudia

After some quick searching I found an Instructable which uses your same sensor and plots the data thanks to a Python script.

You'll need to install Python if you want to replicate this project, but any programming language with a drawing library will work.

  • you can even grab the serial data and plot it with excel – Mark Omo Apr 26 '15 at 15:43
  • yup i've done that! it's just hard to understand what's happening if not in real-time. i am looking to give an audience a sense of what the sensor is doing while it's running. but great idea and thanks! – claudybee May 1 '15 at 16:25

A simple and fast solution would be implement a chart using a JavaScript library called Chart.js. it is simple and you can visualize your data in realtime.

Try node.js to make the back-end by communicating via serial (serialport package is good) and send the data using socket.io.

It is simple and you can set everything in less than 2 hours.

Chart.js

I recently made some video tutorials about this and you see them here. The audio is in Portuguese but you can just skip and go directly to coding sections.
