IR Circuits
This circuit has two stages: a transmitter unit and a receiver unit. The transmitter unit consists of an infrared LED and its associated circuitry.
IR Transitter
The transmitter circuit consists of the following components:
1. IC 555
2. Resistors
3. Capacitors
4. IR LED
The IR LED emitting infrared light is put on in the transmitting unit. To generate IR signal, 555 IC based astable multivibrator is used. Infrared LED is driven through transistor BC 548.
IC 555 is used to construct an astable multivibrator which has two quasi-stable states. It generates a square ..................[:=> Show Contents <=:]

Sensors are fixed at 1km on both sides of the gate. We call the sensor along the train direction as Ëœforeside sensorâ„¢ and the other as Ëœaft side sensorâ„¢. When foreside receiver gets activated, the gate motor is turned on in one direction and the gate is closed and stays closed until the train crosses the gate and reaches aft side sensors.

Due to some unavoidable circumstances, if there is a sudden breakdown of a vehicle between the gate, then the light from laser source does not fall on LDR. It indicates the presence of vehicle and the signal for train should be made RED in order to slow down the train to avoid collision. Then the obstacle should be warned to clear the path.
v) Gate Closing Operation:
Once the microcontroller senses that there is no vehicle inside, then it automatically produces the signal to operate the motor throu..................[:=> Show Contents <=:]

DPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memory that uses 8-bit addresses (MOVX @ RI), Port 2 emits the contents of the P2 Special Function Register. Port 2 also receives the high-order address bits and some control signals during Flash programming and verification.
