Yeah so this is the design which we are thinking so. We are having a power button and the switch  , which is not much ,
and then we are having the  which is to indicate whether the power is on or not. And then there are two kind of things which can be  so one is the button interface which has not been shown because because of lack of time .
So we could not put that. So now where the A_S_R_ decoder is sitting , similarly there are different kind of interfaces which could be there. So there is A_S_R_ decoder which could be there , and then there could be another scroll button scroll scroller , and then there could be buttons , and all of them they will just do the decoding and put it in the math put it in the proper message format. And then there is there is the chip which is sitting , the green one , and it converts it into bit codes , and that bit codes are sent by the infrared device to the receiver.
Okay.
