In case the sensor senses the intruder then microcontroller output turns high.Till this we have completed designing the circuit.Now we want to have an interfacing device which will take input from microcontroller and dial a particular number (say 6 digit) using a telephone.We are stuck here.Which interfacing device should we use to how to implement this logic in our design?? Guys please I really need this.Urgent help is appreciated.Thanks in advance....
