    Electronic Countdown Timer Circuit

    Hi,

    I'm am attempting to make a 10 second countdown timer circuit using a 7-Segment Dual Digit Display. I would, ideally, like it to countdown from 10 to 0; wait for about another 10 seconds and then restart.

    Do you have any idea as to which chip(s) I should use?
    I would gladly appreciate a circuit diagram as well, if possible.

    Thanks!

    Re: Electronic Countdown Timer Circuit

    Hi,

    There are loads of such timers, just search this forum and the web to find a suitable one.

    Most will be micro based so that mean getting a programmer as well.

    Depends if you intend to become involved in micros or is it more a one off project ?

    Probably the simplest and cheapest way is to use an Arduino Uno board that can be programmed directly and has loads of programs ready made.
    Just search on "arduino 7 segment countdown timer"

    Re: Electronic Countdown Timer Circuit

    Thanks for the response. It is for a GCSE project. I'll try and see if I'm permitted to use an Arduino. Thanks again for the help!
