    Hi, firstly I apologise as this will be very basic to you but I am only starting out.

    I want to make a little alarm clock with a snooze function.

    I want to have a switch that pressed once generates a ten minute snooze alarm,
    twice = twenty minutes, thrice = thirty minutes. Each time a different coloured LED comes on and the alarm vibrates.

    I have the following:

    Veroboard
    555
    Logic gate
    Shift register
    LEDs
    A switch
    Pizo motor (for vibration)
    Battery

    Is this enough? And the big question, how do I go about setting it up??

    I have solder, iron, wire etc.

    Thank you in advance for your help

    Yes, just throw all the parts in the blender and see what comes out :)

    I assume you mean not that you want to build a clock (the parts list is not sufficient for that), but just a standalone device that you can energize after your alarm goes off to give you the delayed alarm. Is that correct?

    Hi Bob, thanks for that! Boy, I wish I could just throw it all in a blender - I never could grasp electronics at school!

    I am actually builing a toy, no clock, just a stand-alone alarm you use exclusively for a snooze alarm.
