Thank you for the swift response.You are referring to cell phone service, are you not? Most other internet connections are not where cars are allowed.
Actually i need it from anywhere, i mean within a country, from every spot where internet connection can be found.
Serial.println("turn on at 9:00 pinMode led,HIGH;");
Serial.println("turn on at 9:00");
Can you supply a link to that board? how is it attached to the Arduino?Doesnt matter how is it attached to the Arduino... Im using sim's tx in arduino's rx and sim's rx in arduino's tx, but whatever cause the sim808 turns on without serial connection...
I don't think back EMF if hanging your Arduino since the Arduino is completely isolated from the motor via optocouplers (if your diagram is accurate). How do you know the code is hanging vs just a bug?Disconnecting an inductive load can cause sparks across the relay contacts, which are basically like a klaxon horn of EM noise.
Change your "if" to a "while"Excellent - it worked. I'm really happy for your help.
Overly machinated? Possibly, though as the menu management code base I adopted provided a set of elegant-seeming functions for building the lcd line buffer (concatenation, copying and left and right padding) I thought that that was the best way to do it. These functions are also used elsewhere for formatting content for the lcd.when it comes to LCD's sprintf() and its safer cousin snprintf() rock.
I will take a look at sprintf.
