Best way to store memory? plus other questions.

Hi, I am a basic stamp hobbyist (though now I mainly do javascript and php) and started hitting walls on a new program.
Thanks will be given for the lowest cost solution.

How to store memory (code, variables, binary, you name it)

where to get good ol' pushbuttons (ones that will go right into the breadboard and are nice and small)

LED Light array? (many lights, not so many pins)

Way to measure battery within stamp?


Thanks,
Shane

    You need to be more specific when asking your questions. What do you mean by "store memory"? Can you give examples of what you want to do?

    There are a variety of vendors of electronics components that allow small orders over the internet. Some of them include SparkFun, Jameco, DigiKey, and Mouser. They carry pushbuttons and LEDs as well as lots of other stuff. Parallax has a few items as well.

    Look here under "app-notes" for a description of how to measure battery voltage using the RCTIME statement.

    I store my code in the eeprom.This code will only last for about 100-years according the a manufacture of the eeprom.

    What kind of Stamp are you using? Certain stamps do not support I2C. If you have a fancier Stamp then i would suggest using a EEPROM....Depending on your model you actually have extra EEPROM built into the stamp.

    Ravenkallen,
    All Stamps can use I2C EEPROMs. Some of them have built-in I2C support statements (BS2p series) while the others have to use subroutines to "bit-bang" the I/O pins used. There's a Nuts and Volts Column that covers this topic.

    @Mike...Yes, exactly. I should have mentioned that as well...The bit banged code is a little harder to get used to though. Plus, it does take up some program space. Check out this link.
