Now to check if the number is saved you can write the letter z to display all the numbers. Don’t write a value to the EEPROM inside an infinite loop without any delay or check for user input. #include #include void setup() { //Start serial Serial.begin(9600); while (!Serial) { ; … I/O across block, page and device boundaries is supported. Copy this link. Now you can make an advanced level Security system and use multiple numbers. The amount of the EEPROM memory depends upon which Arduino Model we are using. Most microcontrollers even have EEPROM directly in their circuitry, such as the ATmega328P (Arduino Uno chip), which has 1KB of it. Arduino EEPROM vs Flash. The Arduino’s internal EEPROM is specified to handle 100,000 read/erase cycles. none Note. How to use an external EEPROM and we will talk about a specific EEPROM IC that we are going to use. In this tutorial, we’re going to look at EEPROM memory on the Arduino. First, we will see a little bit about the AT24 Series EEPROMs, the pinout and pin description of AT24C256, write a couple of functions to READ and WRITE data from/to the EEPROM and finally understand how the Arduino AT24C256 EEPROM Interface works. […] Arduino Sketch Example Read Something. The Tx and Rx pins of the HC-05 or HC-06 are connected with the Arduino’s Rx and Tx pins, while the ground and VCC pins are connected with the Arduino’s gnd and 5 volts pins.
