Ph sensor notification through GSM

im using arduino board, GSM board siemens tc35, breadboard,LCD and ph sensor from atlas scientific.

what i understand about this project is,
1) i need to wiring arduino board with LCD through breadborad (done)- but not display anything yet.
2) i need configure circuit for ph sensor that atlas scientific give with ph sensor that i buy.(the wiring is done, becoz the circuit is on)
3) connect arduino with GSM board.

1) with this arduino board, i need to configure 3 thing. that is LCD, ph circuit and GSM modem.. that is posible? or it is normal to used only one arduino or i need more arduino?
2) that my wiring is correct? because my LCD not display the hello world after i burn the coding into arduino. the LCD is on and display the black box. but not the "hello world"
3)how i can test the GSM board, is it work or not?im used hyperterminal. i type "AT" and it just reply "OK". nothing happen after that..

please give me advise and help...

You can connect all device using single arduino. LCD use 6 pin, ph 2 pin, gsm 2 pin. But maybe you can add button or keypad to make more interactive to insert phone. The intelligent function depends on memory. More intelligent, need more memory.

Between 3 device, LCD is most easiest. So you need to success that first before doing ph and gsm.

i struggle to make the LCD work... because the LCD only display black box... not the word that i burn into arduino...

how i want to burn the coding with 3 difference device? if i new coding into arduino, that old coding is save into arduino or not?

You code the 3 device in seperate just to test functionality or get understanding on it. When do a project, the 3 device is operate together, just at the different pin.

Everytime you program arduino, it's overwrite the old code.
