Result and Analysis

The programming for the gsm and hardware is successful for interfacing. The data or result from solar hardware can be send to the mobile phone via gsm on 7.00pm for average voltage and current result automatically. This program also can send the result manually with sending the message to the gsm "voltage" for voltage result and "current" for current result in every time. This programm will be reply for each message to the mobile phone.

Conclusion:

As a conclusion, this program is successfully and can interfacing with the solar hardware. I know how to learn programming for two way communication using gsm to the mobile phone or otherwise. For next step, i will make the design for the poster.

Result and Analysis

The programming for the gsm and hardware not successful for interfacing. The data from hardware can be send to mobile phone, but from the mobile phone send the message to gsm for asking the parameter solar cannot be reply from hardware.

Conclusion:

As a conclusion, i think hardware cannot read for asking from the mobile phone or programming conflict for the programming send to mobile phone. i will find out what the problem in this case as soon as possible.

Conclusion:

              The programming for the push button has been successful to load into PIC. For next step, i will programming for the GSM.

Result&Analysis

• Programming successful for LCD screen 2X16 when the compiler in mp lab not detect another problem in the programming.

Conclusion

• As a conclusion, i know how to program of the LCD screen in PIC 16F887. For next step, i need to program for the push button for select the time.
