Design of Electronic Calendar Based on MCU

The electronic calendar is an indispensable electronic product in People's Daily life, it not only carries the bright culture of 5,000 years of China, but also is an important book to guide the cultivation of the Chinese nation. This design takes the IAP15 series MCU as the core, and the peripheral circuit includes the main control core, wireless module, display module, clock module, temperature and humidity module and other modules. The wireless module adopts ESP series chip to realize the function of MCU networking. The display module adopts OLED to display time, temperature and humidity. The clock module adopts PCF series chips to realize accurate control of time. The temperature and humidity sensor module uses DHT11 chip to realize the collection of environmental temperature and humidity, and simulation on Proteus with hardware circuit is also included.
