Designing and manufacturing the system of turning on and off the headlights by voice on Arduino software

Abstract

The system of turning on and off the headlights by voice on Arduino software was designed, manufactured, and effectively applied for turning on and off the headlights by voice while driving and increasing comfort in cars. The circuit of the car lighting system was designed in which an electronic control circuit was installed basing on the voice recognition signal to connect and disconnect the headlight current to the ground. The electronic control circuit included the VR3 voice recognition sensor and the Arduino UNO R3 module, which was programmed in the Arduino IDE (Integrated Development Environment) programming environment. The voice recognition sensor collected the voice signal and converted it into a digital signal to send to the microprocessor, which was made of an Arduino module. The microprocessor would analyze the voice recognition signal. When the signal matched the previously established voice signal, the microprocessor would send a voltage that would activate the relay of the electronic control unit and the standby current at the headlight pin would be connected to ground to turn on the headlight. The system of turning on and off the headlights by voice on the Arduino software was experimentally operated and the results showed that the system operated stably and the control accuracy reached 100%.
