void loop ()

{
  sensorValue = analogRead (analogInPin);
  writeEEPROM (address, (byte *) &sensorValue, sizeof sensorValue);
 
  byte test2 [2]
  readEEPROM (address, test2, sizeof test2);
  Serial.println ((char *) test2);
 
  addr += sizeof sensorValue;
  Serial.print("analog pin: ");Serial.print (sensorValue, DEC);Serial.print('\n',BYTE); //debug
  Serial.print("address: ");Serial.print (address, DEC);Serial.print('\n',BYTE); //debug
  }  // end of loop




I'm confused on how to read the int after it has been written. I had the test2 byte in there just so I could try to read something, but all I got out was garbage.

When writing we passed the address of sensorValue (ie. &sensorValue) so you have to do the same thing when reading back. That is:

 int test;
 readEEPROM (address, &test, sizeof test);

That reads back into the 2-byte integer in the same way we wrote the data tout.
