| Abstract | ||
| The work presented in this paper concerned with the design of a new remote control system, which can be used for controlling the on/off of home/office devices using mobile phone. The design consist of two main parts, the first part is a remote mobile phone used to select the home/office mobile and choose the selected tone code (0-9, *, #) from the user according to the selected device. The second part consist of a practical design which contains the fixed mobile phone connected with Dual Tone Multiple Frequency (DTMF) detector, delay and answer circuit and decoder to complete the function of responding the calling and analyze the tone code for control the selected device depending on tone analyzer of DTMF. The practical design which consists of DTMF, decoder and flip flops was implemented using Field Programming Gate Array (FPGA). The system has been worked in high speed action when implemented in Spartan FPGA package and good results have been recorded | ||
