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. This tone is perceived by the Arduino and decoded using a DTMF decoder. The Arduino then directs the IC to drive the motor which causes the motor to move. The motor is operated at different speeds.

Keywords : Dual Tone Multi Frequency (DTMF), Integrated Circuits (IC), Arduino.
