### Project function introduction

* The main control uses esp8266
* The display part uses max7219 to drive the dot matrix to display digital time, and a 1.3-inch OLED to display weather and human-computer interaction
* The clock uses PCF8563M as the clock module, and added Battery
* Use three I/O ports to make four buttons for human-computer interaction
* Use a photoresistor on the ADC port to adjust the dot matrix and screen brightness
* Use a microwave module to detect whether there is human activity, which can be used with the photoresistor to provide night information screen
* and can plug in an mp3 playback module to realize weather voice broadcast
