We attach this ABS system with either lineament of braking system.either hydrolic system or induction braking. In this concept we use one photosensor with infra tearing lighthearted. Infra red light transmit the signal in the air and if at that place is any obstruction and so this light is reflected from the object to the photosensor and further enlistment is on automatically.

in the transmitter components we use infra red led as a transmitter and photodiode as a receiver. This photodiode is connected to the ic 555. ic 555 is a 8 pivot monostable timer ic. Photodiode is connected to the pin no 2 directlly. When pin no 2 become more negative then ic 555 provide a issue to the pin no 3. Pin no 4 and 8 is connected to the substantiating add on. For this purpose we use 5 volt regulated office supply for the ic. For the 5 volt regulated power supply we use ic 7805 regulator to provide a 5 volt regulation. Output of the ic 555 is connected to the H keep going circuit through 2 optocoupler components. Optocoupler is 4 pin ic with 2 pin on either side. In this optocoupler there is one input led and one photodiode in the otherwise side. Optocoupler provide a isolation between the input and output circuit through the optical isolation circuit.
Dc ride is control by the h bridge circuit. H bridge is combination of four transsitor circuit. In the H bridge deuce transistors are npn and two transistors are pnp transistor. With the avail of this four transistor we control the direction of the dc motor automatically.
