AUTOMATIC PARKING LIGHT THIS CIRCUIT IS BASED ON LDR (LIGHT DEPENDENT RESISTOR). NORMALY DURING NIGHT TIMES IN HIGH WAYS WE SEE PLEANTY OF ACCIDENT, EVEN WHEN VECHILE IS PARKED ON ROAD SIDE. DUE TO CONTINOUS LIHTING OF PARKING LIGHT THE BATTERY GET DRAINED OUT. SUDDENLY ALL LIGHT GETS OFF AND WHOLE PLACE WILL GET DARK AND THE VECHILE COMING FROM OPPSITE WITHOUT NOTICING THE VECHILE MEET WITH ACCIDENT. TO AVOID SUCH ACCIDENT, HERE IS A BOOM. DESIGN: THIS CIRCUIT IS CONSISTS OF IC 555 WHICH IS A MAIN PART FOR TIGGERING THE OUT ACCORDING TO LIGHT OF THE OPPSITE VECHILE HEAD LAMP FALLS ON LDR. HOW IT WORKS? ACCORDING TO THE LIGHT THE LDR RESISTANCE VARIES. INTIALLY THE LDR VALUE WILL HIGH (IN DARKNESS) SO A NEGITIVE PLUSE WILL TIGGER THE IC OUT PUT AT PIN NO3 WILL BE HIGH. OUTPUT IS FED Q1 AND SAME SIGNAL INVERTED TO Q2 THERE WILL NO CONDUTION IN TRANSISTOR Q1 AND Q2. WHEN LIGHT FALLS ON THE LDR THE PROCESS IS REVERSED THE TRANSISTOR Q1 AND Q2 WILL BEGING TO CONDUCT AND THE LAMP L1 IS LIGHTED. BY THIS WE CAN SAVE THE VECHILE BATTERY DRAINING SOON. IT AUTOMATICALLY SWITCHED ON BY THE LIGHT OF THE OPPSITE VECHILE.
