The main aim of this project is to design a vehicle anti-collision system using ultrasonic sensor and Arduino UNO. This is a driver-assistance system used to detect the obstacles using sensor and provide the driver with warnings to help avoid a collision. Ultrasonic sensor is used to detect the obstacles and gives the audible alerts through buzzer. This project makes use of a micro controller, which is programmed, with the help of embedded C instructions. This Microcontroller is capable of communicating with input and output modules. The controller is interfaced with two DC motors along with l293d motor driver, which are fixed to the vehicle to control the direction of the vehicle. The system also includes obstacle sensors to detect the obstacles in its way and stop the vehicle automatically. The main controlling device of the project is Arduino Nano Microcontroller. LCD display, Ultrasonic sensor, Buzzer, DC motors long with L293D motor driver are interfacing to the Arduino nano microcontroller. Ultrasonic sensor is used to detect the obstacle in the path of the vehicle and process this data to the Arduino nano. Then Arduino nano will activate the buzzer for alerts and stop the vehicle accordingly. To moves the vehicle using 12V rechargeable battery. To achieve this task microcontroller loaded program written in embedded C language.
