Hey guys! I'm new to the arduino and working with my lcd, so bear with me!
I'm trying to get the excuse generator to work in my code, and I keep getting this error message:

/Users/KaraBucaro/Documents/Arduino/excuse_generator/excuse_generator.ino:40:92: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]

Sketch uses 3,132 bytes (9%) of program storage space. Maximum is 32,256 bytes.
Global variables use 281 bytes (13%) of dynamic memory, leaving 1,767 bytes for local variables. Maximum is 2,048 bytes.

Any ideas of what I can try and do? I'm using a mac, osx latest software, arduino uno.

This is what my set-up looks like, and attaching the code.

Thank you guys!!

Try:

const char *start []= {"I'm sorry but ","Don't blame me ", "Not my fault ","Guess what happened "};

But that's an awful lot of work over a warning. I would just ignore it.

Or handle them correctly:

   Serial.print((char *)"Hello");

The const char * ("Hello") can be cast to a char *, which is what the Serial.print() function expects.

Better still, leave them in flash memory, where they belong

Thank for for the help, I got it figured out and uploaded successfully! Now my only problem is the LED is not turning on, and I have a bar of black boxes.

I'm trying to get the excuse generator to work in my code, and I keep getting this error message:

The only one talking about "error" and "error message", IS YOU!

The compiler just tells about "warning":

warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings]

A warning is NOT an error!

Get yourself informed about the deifference between a "warning" and an "error" in compiling C/C++ code!

A warning does NOT stop the compiler run and continues compiling the code. The cause of a warning might be a smaller coding problem and the compiler tries to guess what you mean and contnues compiling. In your case you are using an old 'deprecated' syntax, that was fully correct with older compiler versions, but creates warning with new compiler versions. After a warning (even many warnings) the compiler tries to recover the problem and continues compiling. Contrary, an 'error' stops the compiler run immediately with an anrecoverable error and does NOT try to continue.
