Simply so, how do you read and write eeprom?

Reading from the EEPROM basically follows the same three step process as writing to the EEPROM:

1. Send the Most Significant Byte of the memory address that you want to write to.
2. Send the Least Significant Byte of the memory address that you want to write to.
3. Ask for the data byte at that location.

One may also ask, how data is stored in eeprom? EEPROM stands for Electronically Erasable Programmable Read Only Memory which is a type of non-volatile memory used in various electronic devices to store relatively small amount of data. The EEPROM allows the data to be read, written and erased on byte level. The ATmega328/P contains 1K bytes of EEPROM memory.

Similarly one may ask, how read and write eeprom in Arduino?

EEPROM Write. The microcontroller on the Arduino and Genuino boards have 512 bytes of EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive). This example illustrates how to store values read from analog input 0 into the EEPROM using the EEPROM. write() function.

How do I clear eeprom?

EPROM typically is burned out-of-circuit in a programming fixture. When the time comes to erase the EPROM, just pop it under an ultraviolet (UV) bulb for 30 minutes, and you're ready to go again. The EPROM's quartz window allows UV light to strike the silicon die, erasing the memory.
