    Hi all,

    I am new in this forum and I wish to find help.

    I have a rectangular area and I am looking for a set of components (i.e Sensors ) to detected if the object inside this area or not.

    The output of the circuit should be suitable for a programming language.

    I want to connect and program the circuit to a basic stamp parallax training kit.

    Any idea, please help!:confused:

    Thanks in advance.

    Take a picture of the blank area and compare it to a a current picture, any differences equal something inside... Threshold of differences will need to factor in environmental changes as well as setting a minimum size to detect...

    You can Google 'camera line followers' to get an idea of what is needed and how it's done...

    Do you mean a specific object, or any object?
