+# Vehicle Accident Prevention System
+
+
+## Aim
+
+To design a Arduino Based Vehicle Accident Prevention System.
+
+
+## Purpose
+
+This project proposes a quite efficient way to prevent road accidents.
+
+
+## Components Required
+
+* Arduino UNO
+* Breadboard
+* Connecting Wires
+* LCD 
+* Potentiometer 
+* Ultrasonic Sensor
+* Servo Motor
+* Buzzer
+* 1 Red LED
+* 1 Green LED
+* 2 Resisitors
+
+## Short Description 
+
+The project deals with prevention of accident by sending alarm and a warning message to the driver if there are other vehicles in the vicinity. It also has a feature of automatic breaking system which turns on when any vehicle is too close than the given threshold distance.
+
+## Workflow of the Project
+
+- The servo motor acts like the breaking system of the vehicle.
+- When vehicle is greater than 3m greater than the subject:
+  - Green LED is turned on.
+  - **Safe Distance** message is displayed on the LCD screen.
+- When vehicle is lesser than 3m and greater than 1.5m close to the subject:
+  - Green LED is turned on.
+  - **Caution Message** is displayed on the LCD screen.
+-  When vehicle lesser than 1.5m and greater than 1m close to the subject:
+    - Red LED is turned on.
+    - **Apply Break** message is displayed on the LCD screen.
+- When vehicle is less than 1m from the subject:
+  - Automatic Brakes are applied.
+  - Green LED is turned on.
+  - **Brakes Applied** messsage is displayed on the LCD screen.
+
+
+## Setup instructions
+
+- Design and assemble the circuit as shown in the image.
+- Check the connections of all the components.
+- Upload the code which is provided.
+- Start the simulation
