Analog Voltmeter: amzn.to/3q3ZqYi

This analog stock ticker uses a galvanometer-style voltmeter and PWM signals from an ESP8266 microcontroller to physically visualize the daily percent change of the S&P 500. It was a really easy project to make, and I hope that others can take this inspiration and hopefully see this project through a bit more fully than I did.
Thank you for watching Christopher's Factory!
