# Sixth Lichuang Electric Competition# Silent Wisdom Home Multifunctional Development Board

* 1. Introduction to project functions

Silent Smart Home Multifunctional Development Board

Onboard ESP8266 (ESP-12F/12S/12E/07S) minimum system;

Tuya WB3S module interface is reserved;

The onboard Hangshun HK32F030MF4P6 minimum development system leads to all pins and download circuits!

On-board devices: digital tube, 0.96 OLED screen, photoresistor, buzzer, two-way relay, WS2812B light strip, RGB light, DHT11, SHT30 temperature and humidity sensor, and DS3231MZ+ clock circuit, satisfying HK32 development and learning!

The OLED screen can be soldered directly to the motherboard, or you can purchase a finished module and plug it into the motherboard's reserved interface!

The onboard devices can be connected to ESP8266 or HK32 for control through jumper cap selection. H32 and ESP8266 can work alone, or they can be selected through jumper caps, with HK32 as the main control and ESP8266 as the WIFI module to complete functional demonstration and development!

*2. Project attributes

This version is a modified and improved version of the aviation training camp work, which optimizes the wiring, corrects the problem that ESP-12F IO16 cannot receive DHT11 data, and replaces the interface with IO2.

* 3. Open source agreement

Programming is my weak point. I hope brothers can communicate and discuss with each other. All the information is open source!

Please fill in during the competition stage↓

*4. Hardware part

This project was designed and drawn using Lichuang EDA, which can be opened directly online to view the details.

*5. Software part

The software is being sorted out:

The implementation functions are as follows:

1. Connect to the lighting platform, and Xiao Ai can control the relay switch

2. OLED can display weather data and current time (the program comes from the Internet, thanks again to the author: zknuwdxy)

3. The buzzer can play the alarm

4. DHT11 temperature and humidity data can be obtained

5. Light up the WS2812B lamp panel

6. Turn on the RGB light

7. The digital tube driver is not completed.

8. Adjusting the brightness according to the ambient light has not been completed.

9. The local clock is not completed

10. HK32 debugging currently has no tools and has not been completed.

11. Function integration is not completed

For the unfinished part, I hope some brothers can guide me!
