Arduino speedometer

Overview

After the project was sorted out, the ESP speedometer was independently open sourced as a project.

Version 3.0: A multi-purpose speedometer developed based on the ATMEGA328P chip. It includes data display, serial port download, lithium battery management, button and other functions. Compared with 2.0, it has added support for 10mm groove photoelectric switch and can also be developed as a separate For board use, it is recommended to use the AD file in the attachment.
