The present invention relates to a bicycle turn signal using a pressure sensor, comprising: FSR402 pressure sensors respectively attached to handles on both sides and a brake apparatus on a bicycle, thereby transmitting a changed resistance value to an Arduino Uno R3 board when a user applies a pressure or actuates the bicycle brake; an LED dot matrix for indicating an arrow or a letter in red on a signboard at the rear side of the saddle and a helmet by using the Arduino Uno R3 board, which calculates the resistance value detected by the FSR402 pressure sensor; a Bluetooth module for helping a communication function of the Arduino Uno R3 board, also communicating with the user′s smartphone; and the Arduino Uno R3 board which controls the FSR402 pressure sensor, LED dot matrix, and power supply unit, thereby allowing event information to be displayed on an LED display through communication between the Bluetooth module and the user′s smartphone. The present invention provides unique effects such as significantly reducing accidents while on a bicycle, and to display advertisements, bicycle riding information, urgent news like disasters, and event information.

    본 발명은 압력센서를 이용한 자전거 방향 지시등에 관한 것으로, 본 발명은 자전거의 좌우 핸들과 브레이크 장치에 각각 부착되며, 사용자가 압력을 가하거나 브레이크에 제동을 걸 때 변화된 저항 값을 Arduino Uno R3 보드로 전송하는 FSR402 압력센서와; 상기 FSR402 압력센서로부터 검출된 저항 값을 연산 처리하는 상기 Arduino Uno R3 보드에 의해 안장 뒤쪽 표지판 및 헬멧에 적색으로 화살표나 문자를 표시하기 위한 LED 도트 매트릭스와; 상기 Arduino Uno R3 보드의 통신 기능을 도와주며 사용자 스마트폰과 통신을 위한 블루투스 모듈과; 상기 FSR402 압력센서와 LED 도트 매트릭스, 전원공급부를 단속 제어하며, 상기 블루투스 모듈과 사용자 스마트폰간에 통신을 통한 이벤트 정보를 LED디스플레이에 표시가 가능하도록 하는 Arduino Uno R3 보드가 포함되는 것을 특징으로 하는 압력센서를 이용한 자전거 방향 지시등을 구현함으로써, 자전거의 안전사고를 크게 줄이고 광고나 자전거 운행 정보, 긴급뉴스, 재난정보 등의 이벤트 정보를 문자로 표시할 수 있는 독특한 효과가 있다.
