Robot Car

This is a smart car device that is able to move by itself without hitting any obstacles. It makes use of an ultrasonic sensor to detect any objects. It also has an LCD display unit which shows the car speed, distance travelled, remaining fuel left in percentage and a servo motor to represent the speed of the car. The car will automatically stop once the fuel is less than 10%.
Whenever nothing is detected in front of the car, the car will move at full speed. When there is lesser space in front of the car, the car will decelerate at half the speed. Once a far object is detected, the car will turn. However, if the object is very near and the car is unable to move any turn, it will stop immediately and reverse.
