EEPROM Library The microcontroller on the Arduino and Genuino AVR based board has EEPROM: memory whose values are kept when the board is turned off (like a tiny hard drive).

8-bit decimal display The code in /multiplexed-display is for programming an EEPROM to be used to decode 8-bit values and drive a 4-digit 7-segment display.

In this blogpost we’ll show you how to store this kind of data on the Arduino so that it doesn’t get erased, just like you would store data on the SSD or HDD on your PC.īuild an Arduino EEPROM programmer. This means that even when the board is powered off, the EEPROM chip still retains the program that.

Reading and Writing Data to External EEPROM Using Arduino: EEPROM stands for Electrically Erasable Programmable Read-Only Memory.EEPROM is very important and useful because it is a non-volatile form of memory.

Optionally, you can have it pre-assembled, and also purchase a pre-programmed Mega 2560. The kit includes PCB, 28-way ZIF socket (option of budget or high-quality versions), header pins, indicator LEDs (one for 'Read' and one for 'Write') and resistors.

It's a simple EEPROM programmer shield, designed to sit on top of an Arduino Mega 2560.This work in the same way as the RAM in your PC. As soon as you pull the plug and the microcontroller loses power, this data will be erased. When collecting or generating data and storing it on a microcontroller, like the one on an Arduino, the data will just be available while the microcontroller is powered.
