This project uses an ESP32 TTGO T-Display to display a clock that uses resistor colors. The intention of this project is to help me memorize the resistor colors so I can read them as well as numbers. I plan to make this also work as a tratitional clock. I can use one of the buttons to toggle the display mode. I would also like to add an RTC. With an RTC, this would make a great travel clock. The TTGO T-Display also already has a battery port and charger.
