[Course Design] Tuya Smart Music Rhythm Lantern

1. Introduction

Tuya smart music rhythm lantern, this design is the final topic of Lichuang EDA circuit design course, which lasts 16 hours. It mainly uses Tuya smart WIFI module to realize the color adjustment of light and music rhythm function. The design basically uses direct plug-in devices, which is convenient for students to weld and easy to implement.

2. Implementation process

1. Create an IoT project. Create a new project on the Tuya IoT platform ( https://iot.tuya.com/ ). The specific operations are as follows. (1) Create a new product (2) Add product functions, just add them all, especially the music rhythm function must be added (3) Select the public version of the APP interface

(4) Select WBR3 module

(5) Select the network distribution mode, configure the network immediately after powering on, keep other defaults, and re-produce the firmware

(6) After producing the firmware, purchase modules for welding and debugging

2. Design circuit

(1) Schematic diagram, mainly composed of DC-DC circuit, WIFI module circuit, RGB drive circuit, and RGB light circuit. The number of RGB lights can be adjusted by yourself. (2) PCB (3) Three-dimensional drawing (4) Physical drawing

3. Course Arrangement

This course has a total of 16 classes, each class is 45 minutes long. The specific arrangements are as follows:

(1) Familiar with Lichuang EDA design software, 6 lessons.

(2) Coursework design, 6 class hours

(3) Welding debugging, 4 classes
