    HI every one
    my name is Mustafa and I'm a second year student at a technical institute, and I have a mini project.

    I need to generate (2 quasi-square signals must be generated. Their frequencies are 3 Hz and 3 kHz approximately)
    this will work with 5 volt

    I need your help

    thanks

    Hi,
    I'm sorry for this, but I have to point it out: "I need a help" is not a good title to put on a post, mainly when everybody that uses this forum is because they need a help.

    Well, you can start by downloading a 555 datasheet here and study the typical applications. It's always one of the best places to work with an IC.

    If you want some working theory, see this.

    With a little electronic experience you can see the schematic and see how it works... It's simple

    Regards,
    Sérgio Gonçalves

    Does the OP wish to use a microcontroller to generate the square waves?
