Abstract: In this paper a new method has been developed to control the operation of a DC motor remotely. It becomes very much advantageous if a DC motor is controlled using a cellphone. In order to do that the proposed method uses a complex programmable logic device (CPLD). The control input of CPLD is given by Dual Tone Multi-Frequency Signaling (DTMF) decoder. The decoder is connected with a cellphone. It becomes very much beneficial as range of controlling becomes very much wider i.e equivalent to coverage area of the service provider. It is known that CPLD provides quick implementation and fast hardware verification. It gives facilities of reconfiguring the design construct unlimited number of times. The function of CPLD is to process the data coming from the output of DTMF decoder and to create proper duty cycle PWM output, which will control the speed of DC Motor. Hardware is implemented using CPLD trainer kit (model: UNI-BSX-M1) and software is written using VHSIC hardware description language (VHDL) as a pattern tool.
Keywords: DC motor, CPLD, VHDL, PWM, DTMF.
