    Looking for information on building a infrared sensor.

    I am just starting to get into electronics and wanted to start with a simple
    project, an active infrared sensor for the driveway. Nothing fancy simply
    to activate a relay when the beam is broken, I have read something about
    modulating the infrared frequency to account for ambient light and would
    like to incorporate that into the project.

    Thanks

    Found this link on google. Involves a 555 timer to pulse the IR led
    to transmit and a receiver module on the other end, or a tuned band
    pass filter if you want to learn about filters.
