This tutorial presents step-by-step instructions on how to plot live data coming from the arduino using Python with matplotlib. We use the BMP180 pressure sensor to stream temperature and pressure data from the arduino to Python. This requires pySerial, drawnow, numpy, and matplotlib, which we have shown how to install in earlier lessons. See complete description and code at http://www.toptechboy.com and look at Python with Arduino LESSON 11.
I am Paul McWhorter from toptechboy.com and I will be putting together a series of tutorials on use of the Arduino microcontroller.
