app.js listens to port 5555 for any UDP traffic and forwards to port 8000
index.html decodes the incoming arraybuffer and pulls one element. Currently hard coded. Then uses smoothie.js to visualise. Lag is around 200ms
TODO: -- incoming UDP stream is from my phone's sensors. I'd like to include a checkbox of sensors to visualise, so have to dynamically pull the elements from the arraybuffer. (three for accelerometer and gyro)
