Will test it out.

Running out of memory - suggestions?

Two highly effective and absolutely sure ways to solve this problem:

1) shrink your code;
2) move to a bigger chip.

Will test it out.

Arduino 1.5.1 r2 runs normally on my windows 7, 32 bit machine. I don't have an arduino at hand to test the upload but code compiles fine.

Not many fixed strings but I can delete them.  Attached is my sketch:

The warning message from the IDE very helpfully told you the first thing you needed to do, i.e. use the F() macro for all those string literals you pass to Serial.print() and Serial.println(). Looking at your code, I see that you have ignored that advice. Why are you asking for help here instead? If you don't understand what the message is suggesting, and can't understand it after doing some research, you should say so.

Hello...I thought I did say so:

What is PROGMEM or F("text") macro and how do I use in my sketch?

Reply #6 mentioned it:

Serial.println(F("This string will be stored in flash memory"));

Put F("xxx") around strings and they stay in program memory and are not copied into RAM. Did you read the linked page?

Thanks a lot Nick.  You are always very helpful.
