CPLD Based Speed Controller of a DC Motor Operated Through Cellphone

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.
