Overview
Learn to plot live data from an Arduino using Python and Matplotlib in this comprehensive tutorial. Explore step-by-step instructions for streaming temperature and pressure data from a BMP180 sensor to Python. Master the use of pySerial, drawnow, numpy, and matplotlib libraries to create dynamic, real-time graphs. Follow along as the instructor guides you through programming the sensor, printing data to Python, splitting data into variables, and creating functions for drawing and updating live graphs. Discover techniques for setting axis labels, adding legends, and plotting multiple data points simultaneously. By the end of this lesson, gain the skills to visualize Arduino sensor data in real-time using Python's powerful plotting capabilities.
