"基于STM32单片机的自行车刹车转向灯设计"

to control the full-color light beads and infrared laser light, to indicate the braking or steering of the bicycle. This paper first introduces the functions and characteristics of the STM32 series chip and the ADXL345 acceleration chip. Then it details the hardware and software design of the brake light system. The challenges lie in the hardware design issues and considerations, with a focus on the process of assembling code using modular programming in software design. After debugging and analyzing the results, the design successfully achieves the functions of automatically illuminating the full-color light beads when braking, and triggering the infrared laser light before steering to produce a noticeable steering signal, meeting the design requirements. The paper concludes by summarizing the problems encountered during the design process and the solutions.Keywords: STM32, ADXL345, bicycle brake light, steering light
