    Hai friends.....

    i am an young entrepreneur.i am doing coffee vending machine controllers.


    it is not exactly a uniform circuit.it is only a small level circuit found by me.that is one dc motor & 8051 micro -controller.


    the operation of the circuit is ,the delay-time is already pre-defined in the microcontroller.the delay -time only depends on the the cup size.one dc motor is connected to mc.when the input of mc is high. o/p is high i.e motor is turned on.the liquid or any liquid materials get out of bowl.

    simultaneously,the delay function is performed.if the delay function is complete,the motor is turned-off.i.e the motor will be in initial position.

    my doubt is ,is it possible to make a timer circuit without using dc motor ?

    at the same time do i use electronic volve instead of dcmotor?

    program:

    #include<regx51.h>
    void main()
    void delay unsigned int time()
    {
    int c=0;
    if(p0.1==1) /*switch input*/
    {
    p1.0=1;/*motor input turn-on*/
    delay(20ms);
    p1.0=0;
    /*motor input turn-off*/
    /*in between gap the liquid material is get out*/
    }
    else
    {
    p1.0=0;
    }
    }
    void delay unsigned int time();
    {
    int i=0;
    for(i=0;i<=20;i++)
    {
    c++;
    }
    }

    do u mean to ask "is it possible to make a timer circuit without using controller?"

    use dc motor with dc motor driver(such as L293d).
    I have done same project "Micro controller based intelligent tea maker".

    We use a dc motor based self made valve for powder flow and solenoid valve for liquid flow..........
