I'm trying to activat/de-activate a SINGLE electrical device using a PIC and control commands from a standard DTMF telephone set. I have found a circuit diagram and explanation of how it works but don't understand what is taking place after reading through it. Can someone give me the circuit diagram for activating just ONE electrical device instead of the four shown in the diagram of the link attached please?. Thanks.
