1. Team introduction: We are a sophomore sand sculpture team from Sun Yat-sen University. We use this competition to do some cool tricks. Members: Zhang Yang, Zhang Yangming, He Yuhan.
2. Since we moved to a new dormitory with four rooms, we chose the direction of smart home and renovated the dormitory to a certain extent. Without modifying the original circuit of the dormitory, we made it as beautiful as possible while ensuring safety.

1. Describe the details of the project.
The renovation content includes ① decoding the Midea air conditioner in the dormitory, and then realizing remote control through the lighting platform to achieve pre-cooling of the air conditioner and instant cooling after returning to the dormitory.
② Make small changes to the circuit of the socket, add a relay, and obtain the time through the Internet. It can be used to make reservations with the egg cooker, heat breakfast at a scheduled time, and sleep for five more minutes.
③ Add homecoming welcome voice, flirty words, and Internet slang, switch modes according to time, and connect the lights to control the rudder to turn off the lights at night, eliminating the trouble of turning off the lights and crawling into bed in the dark.
* 2. Describe the challenges faced by the project and the problems solved.
The main challenge is that the time is tight. After all, the Level 4 exam is on the 19th, and it is difficult to coordinate the work progress with the team members during the epidemic at home; the other challenge is that it is the first time As for the drawing board, although Lichuang's platform resources and prices provided great convenience, I still drew the board several times due to lack of experience.
Problems solved: Feedback from roommates on the pain points of dormitory life, decoding of air conditioners, access to lighting platforms, time acquisition, and beautifying arrangements.
* 3. Describe the key hardware involved in the hardware and software parts of the project
: NodeMCU, ESP8266 chip, DY-SV17F voice playback chip, 4 ohm 3 watt speaker, miniature human body sensor, panel board, infrared receiving tube, transmitting tube, triode, AMS1117
power module and resistor.
Software part: Blinker platform access, IRremote library realizes infrared emission, modify NTP library to obtain Beijing time, and switch operating mode according to the current time.
