    Hi people,
    my friends and I are stuck in the electronics dept of a project we are making. The requirements are as follows:
    1) A continuity(or any sensor) is activated.
    2) This sets the timer circuit on.
    3) After five sec, the circuit delivers current to a little motor.
    We've been surfing the web for days and we found many good options. We tried the 555, but it ended like..totally...not working. :S
    Could you please help?

    Welcome..

    Why don't u try the 555 timer circuits here, ebooks in AAC

    It's called a delay-on-make circuit or relay in commercial circles. My first suggestion would have been a 555...and still is. Can you post your "not working" 555 circuit.

    with the help of microcontroller you can do the same

    Yo guys, thanks a lot, replies were super fast. Thanks again.
    @Bertus. Gr8 advice. :) That thread taught me much more than a 2 hour lecture would!
    @KMoFFett What we did was pretty simple, took up a schematic on [http://www.kpsec.freeuk.com/projects/timer.htm], watched "How to solder on youtube", bought the soldering iron and the next day we had a somewhat similar circuit. Rookies at work. :D
    @Prateek Thnks mate. Could you elaborate? [First semester, first year electronics stud speaking xDxD]

    @KMoffett As you guess, soldered joints were "rookish", and there's a gr8 chance, that that is where we messed up.[And, for the capacitor, we used a polarised/radial one...:s]
    Prateek mentioned microcontrollers, what are on your views? Easier?
    Could you suggest some good beginner's book about Microcontroller programming?
    Hols are coming up, and that spending the summer with chips sounds pretty cool :D

    Micro-controllers are great. A lot of functional power in a small package. I would recommend that you take time to have fun learning how to use them. Some people use circuit simulators to develop and modify circuits designs. I like breadboarding to see if the design will work with real world components...http://www.youtube.com/watch?v=oiqNaSPTI7w This would be a good way to test your current application. However, you will still have to eventually learn how to assemble the hardware on perf or printed circuit boards. There tutorials on the web like this to help...like: http://www.boingboing.net/2010/06/24/makes-circuit-skills.html And, of course we're here to answer your specific questions. :)
