global system for mobile application (GSM) controlled robot

Here, i m present  one of the advantage  of mobile  .hence  all the mobile keypad having there separate  tone dtmf(dual tone multiplexing frequency) on the basis of it we construct gsm controller.

.

complete circuit diagram given below ,we are using dtmf receiver ic (ht9170) to download  datasheet .
