This home appliances control or home automation project also uses the same DTMF decoder circuit section with little modifications to control home and office electrical appliances. Just connect your cell phone headset (headphone) jack to the mobile phone and then mobile will control electrical appliances and electrical equipment through the DTMF key pad of your cell phone. Here for demonstrating, we are controlling an electrical bulb using this circuit project but you can extend this circuit to control many electrical devices with some modificat ....etc

DTMF Based Interfacing and Control of Induction Motor using TRIAC



The AC induction motor is the most commonly used AC motor in industrial application because of its simplicity, rugged construction, and relatively low manufacturing costs. The reason that the AC induction motor has these characteristics is because the rotor is a self-contained unit, with no external connections. This types of motor devices its name from the fact that AC currents are induced into the rotor by a rotating magnetic field.
Our project d ....etc

Telephony Communication
DTMF decoder

This circuit detects the dial tone from a telephone line and decodes the keypad pressed on the remote telephone. two distinct frequency tones make up the DTMF(dual tome multiple frequency), and hence the name. The the dialer and the telephone exchange communicate one way through the DTMF communication.the tone generator and the tone decoder consist of a complete communication setup. In this project, IC MT8870DE is used to decode the input dial tone to the dialled numbers. These digital bits can ....etc
