Ardunio Program

There are 5 bytes and 8 bits of data that can be send to or receive from iPhone :

Data received from iPhone will be stored in " received_data[n] " ( n= 0 to 4 ) .

Data for sending to iPhone will be stored in " data2send[n] " ( n= 0 to 4 ) .

8 bits received from iPhone will be stored in " received_bits " .

8 bits for sending to iPhone will be stored in " bits2send " .

You have direct access to all these bytes in your program. It can be read or write on them when it needs.

Following instruction codes can be used to read/ write bits :

bitRead(received_bits, x); // x= bit number(0 to 7)

bitWrite(bits2send, x,y); // y= bit value(0 or 1)

Implement following codes in your program. There is a test program in main routine ( Void loop() ) . This will read data from iPhone and send them back to iPhone again. So, if you make a change in "Set bits / Set values" on iPhone then "Monitor bits / Monitor values " will be changed accordingly.

After test completed , remove test program from main routine ( Void loop() ) and put your own program.
