Data Graph

For my project viva I need to do a demo of the Gumsense. I’ve set it up to log readings at 1 second intervals from a potentiometer which I shall twiddle around. It sends them over wireless to my laptop, which sticks them in a mysql database using a php script. A mod_python script then uses matplotlib to plot them:

Horizontal axis is seconds. Vertical axis is reading – in ADC counts (out of 4096).
