this would be my concept..i want to determine that my input on the coin slot would be accepted if the party that i would be calling picked up the call and the display will be counting on a certain time for example "0:05.00"..that concept be the same as a prepaid phonebooth..
any ideas on how to interface Telephone with PIC? I've been thinking of using DTMF decoder like MC145436 (DTMF Decoder)..and I will be using also coin slot for this.Anyone?!:D
