Abstract:
In this project we show how we control multiple systems using one wire system. To control with one wire system is a smart control system. There is only one wire between transmitter and receiver circuit. It is possible to control the electrical appliances with the help of mobile control also. In this we use one DTMF generator circuit and one receiver circuit. DTMF generator circuit transmits the signal to the receiver circuit. Receiver circuit receives this signal and then controls the electrical appliances circuit with the help of relay coil.
