This particular project demonstrates how to write some text starting from a particular memory location of the internal EEPROM of the Arduino and later read the entire EEPROM memory and display it on any serial monitoring software or using the Arduino’s serial monitor itself to find the same data once written. When the serial port of the microcontroller is connected to the PC and the incoming and outgoing data is monitored using software and displayed in a window, it forms the simplest text user interface (TUI) setup for the microcontroller. The serial port of the microcontroller provides the easiest way by which the user and the microcontroller can write their data in the same medium and both can read each other’s data. The Arduino can be interfaced with the other devices with the help of its digital pins, analog pins and with the help of serial communication protocol.

The memory size varies with the Arduino boards and the microcontroller used in them. The Arduino board has an AVR microcontroller in it which also has a built-in EEPROM memory. The EEPROM memory is also used to save the data before the system switches itself off so that the same data can be retained next time when the system is turned on. Most of the microcontrollers have built-in EEPROM with reasonable memory size so that for small kind of applications an extra memory chip can be avoided.Ī microcontroller uses the EEPROM memory to store its data like sensor value, or a particular count or image data for a long period of time uses the EEPROM memory. The EEPROM comes in small sized chips which can be interfaced with microcontrollers in a system. Once programmed the data it will remain in the memory for a very long time even if there is no power available. A kind of Read Only Memory (ROM), which can be written and erased by means of electrically programming the data, is called Electrically Erasable Programmable Read Only Memory (EEPROM).
