In this project e show the concept f auto braking outline. In this system we make work of superstar sensor base technology. When vehicle move on the road and in the case of abrupt braking sensor sense the prohibition and adjacent offer a braking system. We attach this ABS system with every lineament of braking system.either hydrolic system or induction braking. In this concept we use one photosensor with on a lower floor tearing lighthearted. Infra passing light transmit the channelize in the air and if at that place is any deterrent and so this light is reflected from the bearing to the photosensor and further enlistment is on automatically. [pic] in the transmitter components we use infra red guide as a transmitter and photodiode as a receiver. This photodiode is machine-accessible to the ic 555. ic 555 is a 8 pivot monostable horologe ic. Photodiode is connected to the oarlock no 2 directlly. When pin down no 2 become much negative then ic 555 provide a slue to the pin no 3. declension no 4 and 8 is connected to the substantiating work on. For this purpose we use 5 cinque regulated stance tag on for the ic. For the 5 volt regulated power supply we use ic 7805 governor to provide a 5 volt regulation. Output of the ic 555 is connected to the H hold off going circuit with 2 optocoupler components. Optocoupler is 4 pin ic with 2 pin on either side. In this optocoupler there is one commentary led and one photodiode in the otherwise side. Optocoupler provide a isolation between the arousal and output circuit with the optical isolation circuit.

Dc ride is control by the h link circuit. H bridge is combination of quatern transsitor circuit. In the H bridge deuce transistors ar npn and two transistors are pnp transistor. With the avail of this four transistor we control the direction of the dc go automatically.
