Learn how to create a voltage divider using a potentiometer connected to an Arduino and model a real-time analog voltmeter in vPython. Explore the process of reading voltage from the potentiometer's center tap, transmitting binary values to Python, and constructing an animated 3D model that represents live voltage measurements. Gain hands-on experience with Arduino programming, data transmission, and vPython visualization techniques. Cover topics including Arduino code development, importing necessary libraries, utilizing label and position commands in vPython, and adding informative labels to the 3D model. Conclude with a practical homework assignment to reinforce learned concepts and encourage further experimentation.
