%X The importance of the speed control of DC motors inmanufacturing industries like plastic, textile, chemical andpharmaceutical hardly needs any emphasis as it ensures efficientand consistent production. In this paper, the authors presentimplementation of a hardware circuit which is designed forremote speed control of a DC motor by using Dual Tone MultiFrequency (DTMF) tone of mobile phone. The hardware circuitincludes the use of DTMF decoder IC MT8870 and Relay driverIC ULN2003. The mobile keypad keys have been mapped to thespeeds of ¡®High Speed¡¯, ¡®Medium Speed¡¯, ¡®Low Speed¡¯ and ¡®Stop¡¯to regulate the speed of DC motor.
