I'm writing a sketch where I need to have the Arduino "remember", when turned off, the value of two variables. Each variable will be a 0 or 1 (Low or high). I looked at the sketches for eeproms but they all seem to use serial pins. Is there anyway to store the values on power down and recall them on power up?
You can use the standard functions to read and write EEPROM.

Take a look at the examples for the EEPROM library which comes as a part of the IDE. It is how you will use the internal EEPROM.

It is easy to recall values on power on. You cannot predict the power off, so you need figure out when you want to store the values.
