In day-to-day life road accidents goes on increasing due to varies reasons. Some road accidents may cause due to chasing between two vehicles. We avoid these kinds of accidents by providing some precautionary methods using ultrasonic sensors.  Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor. These sensors calculate the time intervals between sending the signal and receiving the echo to determine the distance to an object. If the distance of the vehicle is too small then this vehicle is automatically control the speed of the vehicle which avoids the potential risk of the accident.

The main controlling device of the system is a Microcontroller. Ultrasonic sensor, buzzer and DC motors along with l293d motor driver are interfaced to Microcontroller. The microcontroller gives an alarm if distance is less than predefined limit from obstacle. If the sensor detect obstacle this data is fed as input to the micro control and microcontroller stop the vehicle ignition automatically. Here relay works as a switch to on/off the ignition. To perform the intelligent task, Microcontroller is programmed using embedded ‘C’ language.

Now a day’s technology is running with time, it completely occupied the life style of human beings. It is being used everywhere in our daily life to fulfil our requirements. We can not only increase the speed of life but also increase security with good ideas by making use of advanced technology.

In our project we use high power LED’s as head light for the vehicle, One LDR detects the intensity of surrounding light, particularly fog, while the other LDR detects the headlights of oncoming vehicles. When high-intensity light from an opposite vehicle is detected, the microcontroller reduces the headlight brightness to minimize glare, enhancing safety. high power LED’s as a source of head light. LDR is a special type of resistance whose value depends on the brightness of the light, which is falling on it. It has resistance of about 1 mega ohm when in total darkness, but a resistance of only about 5k ohms when brightness illuminated. It responds to a large part of light spectrum.

The controlling device of the whole system for the vehicle is an Arduino UNO Microcontroller to which LDR sensor module, High power LED is interfaced to the Arduino UNO microcontroller. When two vehicles oppose each other, the intensity of head lights falls on the LDR sensor and automatically the intensity will be reduced. This system avoids accidents due to high intensity head lights of the vehicles. Ultrasonic sensor is used to detect the obstacle and activate the Buzzer for alerts and also stop the vehicle automatically.

The robot uses IR sensors to sense the line; an array of 2 IR LEDs (Tx) and sensors (Rx), facing the ground has been used in this setup. The output of the sensors is a digital signal which depends on the amount of light reflected back, this signal is given to the PIC Microcontroller.

Line follower is a machine that can follow a path. The path can be visible like a black line on a white surface (or vice-versa) or it can be invisible like a magnetic field. Sensing a line and maneuvering the robot to stay on course, while constantly correcting wrong moves using feedback mechanism forms a simple yet effective closed loop system. Practical applications of a line follower: Automated cars running on roads with embedded magnets; guidance system for industrial robots moving on shop floor etc.

The controlling device of the whole unit is PIC Microcontroller to which input and output modules are interfaced. The Microcontroller is programmed in Embedded C language which intelligently performs the specific task. Here, the Microcontroller gets input from the line sensor attached to the robot.
