Multifunctional desktop ornament

1. Project Overview :
The main controller uses an ESP32S3 microcontroller, and the screen is a 1.69-inch touchscreen.
It connects to Wi-Fi, obtains time and weather information, plays audio and internet radio, displays the spectrum, synchronizes audio with NetEase Cloud Music playlists, and uses Dragonfly Radio for radio data.
It works with a host computer to project the computer screen.
It monitors the activity interface of the open-source plaza and the dynamics of Bilibili's EDA platform, providing pop-up notifications for new information, ensuring no JLCPCB activities are missed.
The casing is lamp holder style and can be used as a night light.
 
2. Circuit Description:
The main controller uses an ESP32S3 microcontroller with Wi-Fi and Bluetooth. The peripheral circuit is simple and well-suited for this project. An
 
AMS1117-3.3 converter is used to convert 5V to 3.3V for system use, with a maximum output current of 1A, which is sufficient.
 
The 1.69-inch touchscreen provides direct and convenient interaction, but the interfaces are difficult to solder and can strain the eyes.
 
Audio output is handled by the MAX98357. The SPEAKER_SD output is 3.3V high. After voltage division by R2 and an internal 100k resistor, SD_MODE controls the output of each channel to be half for the left and half
 
for the right. RGB three-color LEDs offer controllable color and brightness, with a simple control method requiring only one I/O port. The
 
 
LEDs automatically turn on when the light dims, based on ADC readings . The main
 
project
page displays the time and weather, and can display the spectrum when audio is playing in the background.
 
 
The LED color and brightness can be set, and
the system continuously monitors the activity page of the open-source plaza and the Bilibili EDA account, displaying pop-up notifications for new activity.
 
 
The music playback interface allows selection of NetEase Cloud Music playlists and Dragonfly Radio
 
 
, and can be projected onto a small TV screen. It can also be used as a secondary screen for background window projection with the host computer.
