    What method have you considered for identifying the individual tools? Can you give us a better description of the process? How is the toolbox to be modified?

    You are counting up when they come in, and counting down when they leave, each using a different exit. Correct?

    I've seen this school problem posted before by other people.

    The problem is distinguishing a tool from a hand.

    The toolbox is just a metal box...tools is placing inside the box wif specify indivisual slots...so when u remove the tools for the box....there will be a sensor and will activiate the counter....if u replace the tools back..sensor will sense the tools and counter reset to 0....problem is ..wat if i keep touching the sensor....just like i park my car in and out....the counter will keep clocking?
