    Our problem is project proposal in Logic Circuits. 4th year Coe po ako
    Can you proposed some project about or using Logic gates and circuits? medyo kailgan na po nmn 2 these thursday. T_T
    minimum budget only.

    Next is the Control Circuits which we need to create a 4 story elevator which the have a 2 door. I read some topic in these forum but im confused T_T could any one can show a schematic diagram and it part

    Sobrang pressure na po kc talga eh. wal na ako makitang way/ T_T

    You need to be more specific.

    In many cases it is cheaper to use discrete logic over logic gates. For example diode logic can be used in limited circumstances.

    Ser. is like a Project proposal in my case these is our final project in logic circuits he say that we need to create an application using logic gates or logic circuits.

    Okay then... you want to create a logic circuit using logic gates?

    Try making a TTL clock; a digital clock using entirely digital logic, no microcontrollers or dedicated clock ICs.

    Yes ser

    Thank YOu so much. Ser if you don't mind can you give us the Schematic Diagram of the TTl Clock? and the parts so we can canvass for the payment. Thank You ser.

    No.

    You are the one getting the grade. You must do the work.

    There are plenty of other TTL clock projects on the internet with schematics. However your teacher will realise if you have copied something and are unable to explain its function or how it works.

    Start with an oscillator signal to keep time. Then develop the circuits to divide time into hours, minutes, seconds. Then, devise a way to display these. Perhaps on LED displays.
