    hi all,i am simulating a circuit in proteus.in my circuit i have an IR transimtter and receiver but i don't find them in the software.can you help me? plz

    thanks.

    ps:i also tried with multisim,but same thing.

    In my proteus, there is the device "IRLINK" which is the IR transmitter and IR receiver in one package.

    I have never used it before and not sure if it would work in your circuit. For simulations you can use opto-coupler to simulate the function. Attached are the devices.

    what's an optocoupler exactely?

    An IR LED closely optically coupled with a photo-transistor, but isolated entirely from each other on the electricity/signal side. They are used to isolate signals from a high voltage side of a circuit from the low side. Used in switching power supplies and other applications.

    Essentially, an IR Pair, but encapsulated into a 4 or 6 pin DIP package so outside light doesn't interfere.

    The transistor types (rather than demodulator/gate types) approximate a discrete IR Pair fairly well.

    but i need the receiver and the transmitter to be discrete if possible.

    They can be in the actual circuit. An optocoupler approximates one for simulation.
