im using arduino board, GSM board siemens tc35, breadboard,LCD and ph sensor from atlas scientific.
what i understand about my project is,
1) i need to wiring arduino board with LCD through breadborad (done)- only display black box 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...
