    Hi All,

    I'd constructed a IR transmitter and receiver. But I don't know how to check the hardware. I've heard that this can be check using a LED. The LED will be light on if no IR ray and light off if receiver received IR ray. Can anyone teach how to construct the testing hardware?

    Thanks

    You can use any digital camera to tell if your IR emitter is operating.

    Hi hgmjr

    I plan to include a LED at the receiver side.
    to make sure IR ray is receive at the receiver well.
