# Sixth Lichuang Electric Competition# Voice control RGB small desk lamp-STM32 version

1. Description

Voice controlled RGB small desk lamp-STM32 version. 2021 Lichuang EDA Summer Training Camp Works. STM32F031 control chip, offline speech recognition module-Qiyingtailun-CI-C22GS02S (1122 standard patch board), controls RGB three-color LED lights.

2. Hardware circuit

Please refer to the specific project for hardware circuit design. It mainly includes the power supply part, voice module, microcontroller minimum system, and LED light drive circuit. They are all basic circuits. If you have any questions, you can communicate with me at any time.

5. Postscript

1. The use of microcontroller programming is mainly the analysis of serial port programs. In fact, the voice module itself can also realize control functions. Due to time constraints, I did not study it carefully!

2. The hardware circuit can realize brightness adjustment and color adjustment through programs. Interested friends can develop their own programs.
