I will also explain how to make an advanced level project based on the Arduino and Bluetooth Module for storing

I will explain in detail the Arduino EEPROM Read and Arduino EEPROM Write operations. We will cover the extreme basics including storing a string message in the Arduino EEPROM and then reading and erasing the stored message.

The following figure shows what weвЂ™re going to exemplify:Д¬opy the following code to the Arduino IDE and upload it to your Arduino board. In this example, weвЂ™re going to show you how to make the Arduino remember the stored LED state, even when we reset the Arduino or the power goes off. Example: Arduino EEPROM remember stored LED state It wonвЂ™t write on the EEPROM again, as the value currently saved is the same we want to write. You use the EEPROM.update() function as follows: EEPROM.update(address, value) ДЄt the moment, we have 9 stored in the address 0. It only writes on the EEPROM if the value written is different from the one already saved.ДЄs the EEPROM has limited life expectancy due to limited write/erase cycles, using the EEPROM.update() function instead of the EEPROM.write() saves cycles. The EEPROM.update() function is particularly useful. This would return 9, which is the value stored in that location. EEPROM.read(address) ДЇor example, to read the byte stored previously in address 0.: EEPROM.read(0) This function takes the address of the byte has an argument. To read a byte from the EEPROM, you use the EEPROM.read() function. The first one is the EEPROM location or address where you want to save the data, and the second is the value we want to save: EEPROM.write(address, value) ДЇor example, to write 9 on address 0, youвЂ™ll have: EEPROM.write(0, 9) Read To write data into the EEPROM, you use the EEPROM.write() function that takes in two arguments. To include the EEPROM library: #include Write You can easily read and write into the EEPROM using the EEPROM library. WeвЂ™ll exemplify this with an example later in this post in the Example: Arduino EEPROM remember stored LED state. To solve this problem, you can save the lampвЂ™s state in the EEPROM and add a condition to your sketch to initially check whether the state of the lamp corresponds to the state previously saved in the EEPROM. You want the Arduino to remember what was happening before losing power and return to the last state.

When the power backs on, the lamp stays off вЂ“ it doesnвЂ™t keep its last change.

YouвЂ™re controlling a lamp with your Arduino and theВ lamp is on.

It is specially useful to remember the last state of a variable or to remember how many times an appliance was activated.ДЇor example, imagine the following scenario: The EEPROM is useful in Arduino projects that need to keep data even when the Arduino resets or when power is removed. Applications in Arduino projects вЂ“ Remember last state This means you can read from the EEPROM as many times as you want without compromising its life expectancy. In Arduino, the EEPROM is specified to handle 100 000 write/erase cycles for each position. However, if you need to store more data you can get an external EEPROM. Take a look at the table below: Microcontroller The bytes you can store on EEPROM dependson the microcontrollers on the Arduino boards. How many bytes can you store?Д®ach EEPROM position can save one byte, which means you can only store 8-bit numbers, which includes integer values between 0 and 255. In Arduino, you can read and write from the EEPROM easily using the EEPROM library. The EEPROM can be read, erased and re-written electronically.
