Abstract:- DTMF based motor control is a method which uses Dual Tone Multi Frequency(DTMF) technology to control a dc motor by using a mobile phone.
SPEED REGULATION OF DC MOTOR USING DTMF KEYPAD
Oct 28, 2024 · This specific project seeks to demonstrate a method of controlling a DC motor from a distance with the help of tones which are formed on a mobile phone keypad in the form of Dual Tone Multi-Frequency (DTMF) tones.
Abstract— In this paper, we can control the Robot using Dual Tone Multi Frequency (DTMF) technology. DTMF technology is most useful technique at present days. It is worked on to methods digital signal processing (DSP). Wireless-control of robots uses RF circuit that has the drawbacks of limited working range and limited control.
DTMF Based Speed Control of DC Motor - IJISRT
DTMF based motor control is a method which uses Dual Tone Multi Frequency(DTMF) technology to control a dc motor by using a mobile phone. A call is made to the mobile phone connected to the dc motor and during the course of the call, whatever key is pressed on the mobile phone is heard at the other end.
GitHub - KNITPhoenix/DTMF-Controlled-Rescue-Robot: DTMF …
Here a phone is attached to a DTMF decoder module MT8870 interfaced with AtMega8 microcontroller with PORTD as input and PORTC as output connected to L293D motor driver IC that drives locomotion motor of the robot. AtMega 8 development board is designed and printed using photo-lithography.
Dtmf controlled robot using AVR - Tutorials
In this tutorial we will see about building a simple dtmf controlled robot. Whenever we make a call, and press keys, dtmf tones are generated and transmitted. The tones can be easily decoded using a IC like MT8870. This enables a lot of possibilities for …
This project is mainly concerned on remotely controlling the speed of DC motor using DTMF technology. DTMF technology has been used to control of speed of a DC motor by changing its voltage level from anywhere of this world via mobile network.
