Laser page turning pen

Overview

This work uses STM32F030F4P6 as the main control, and the XM04 Bluetooth module is configured as a Bluetooth keyboard to achieve the laser page-turning pen effect. The three buttons are laser, previous page, and next page. The weight and length are similar to those of laser pointers on the market, and it is equipped with a lithium battery that can be charged through the Type-C interface.
