Purpose of our course project is to develop DTMF signal controlled house monitoring
system based on PIC Microcontroller. The device is connected to phone line and is controlled by
DTMF signal emitted by DTMF encoder in stationary or mobile phones. In presence of incoming
call the device pick-up the phone and answer the call connecting to the line. User can press
buttons and control the system remotely. Function of keys should be known initially (read
manual in appendix B). The functions are:
· speakerphone monitoring (you can lis ....etc

Abstract
In this project, we present controlling of a Robot using DTMF technique.
The robot is controlled by a mobile phone that makes call to the other
mobile phone attached to the robot. In the course of the call, if any button
is pressed, tone corresponding to the button pressed is heard at the other
end of the call. This tone is called dual tone multi frequency tone (DTMF).
Using DTMF code, direction of motion of the robot can be controlled by
mobile phone. Robot has a RF camera that transmits an actual video at the
operator ....etc

SYNOPSIS
Dual-tone Multi-Frequency (DTMF) signaling is the basis for voice communications control and is widely used worldwide in modern telephony to dial numbers and configure switchboards. It is also used in systems such as in voice mail, electronic mail and telephone banking.
The detector part of early DTMF systems consisted of analog implemented bandpass filter banks, which were tuned to the eight standard frequencies. As analog lines as well as many other analog systems were converted to digital, researchers became ....etc

for EE382C Embedded Software Systems
Abstract
Dual-tone Multi-frequency (DTMF) signals are used in touch-tone telephones as well as many other areas such as interactive control, telephone banking, and pager system. As analog telephone lines are converted to digital, researchers became interested in digital DTMF detectors.
There are many digital DTMF detecting algorithms, but most of them do not comply wit ....etc

a circuit of a remote control unit which makes use of the radio frequency signals to control various electrical appliances. This remote control unit has 4 channels which can be easily extended to 12. This circuit differs from similar circuits in view of its simplicity and a totally different concept of generating the control signals. Usually remote control circuits make use of infrared light to transmit control signals. Their use is thus limited to a very confined area a ....etc
