    hello every one,,,

    I just want to help me to find the layout for this circuit shown below because all connections between the elements are not appear.

    thanks,,,:)

    Am I understanding this correctly? The dark green blocks represent objects going by on a conveyor belt? The orange block is an IR photo diode and the purple block is an IR photo-transistor and is used to detect the objects due to light blockage of the object? The dark aqua block counts pulses and drives the LCD accordingly. Is this correct?

    yes,correct

    It's an object counter using microcontroller

    but I need to the layout for this project,because I want to make it and give it to my college.

    If someone just hands you a finished project to build, you won't learn very much.

    The whole point of going to school is learning things by doing them, and proving that you can accomplish what you set out to do.

    If you cannot complete the project on your own, you really need to start studying instead of trying to take "shortcuts".

    Thank you mr.SgtWookie

    I hope to help me to start it,because I never worked with the microcontroller befor.

    thanks

    We will help you find the 'right' information to read and study, but in the end it is up to YOU to apply that knowledge and create the specific circuit you need.

    Examples of how to build a circuit that will condition or somehow change a signal into another form. Design examples from other circuits that are similar in function and construction to the one you are building.

    Start by breaking down the 'blocks' you have above into separate projects of their own. List what you can't understand and draw the portions of the circuit that you are able to. Do this for each section. You might find that you can actually build about 50% or more of it right now. :)

    Then pick a starting point and dig in. We'll be here for hints and direction. Do you want to learn, or cheat?

    You need to be familiar with microcontroller programming and interfacing, and with your specified micro-controller in particular, moayad. If you're not, you might consider taking a course.

    The input of the circuit is very simple. Just a photodiode and a phototransistor pointing at each other across the conveyor belt. The program is simply to count the pulses. The output requires you to be familiar with your display device and send it the appropriate signals.
