It is an Arduino based safe parking system for four-wheeler. It contains seven LEDs and a ultrasonic sensor through which driver can understand the distance between the vehicle and other object or wall so that he can safely park the vehicle without crash. This device can be place in the parking place to avoid crash with other objects or wall. It measures the distance between the vehicle and sensor and will indicate through the LEDs. Sequence of the LEDs indicates the distance and inform the driver about the vehicle to park safely. If the vehicle is far away from the sensor which is placed in the wall none of the LEDs will glow which indicates that the vehicle is far away from the wall i.e., almost above 100cm. If one green LED glows it indicates that the vehicle is 90cm away. If two green LED glows it indicates that the vehicle is 80cm away. If three green LEDs glows it indicates vehicle is 70 cm away from wall or other objects. If there is further movement in the vehicle then a yellow coloured LED will glow that means; that the vehicle is 60 cm near to the wall. At this point, the driver has to move the car very safely and slowly. After further movement in vehicle, the red LED will glow which resembles that the vehicle is almost near i.e., 50 cm away to the object or wall. So that he can slow down the vehicle next another red LED glows says that the object is 40 cm close and again another Red coloured LED glows saying that the object is 30 cm away so that he can stop the vehicle and park safely.
