In this video, we'll talk about how you can connect multiple EEPROM memory modules to the Arduino. Let's analyze the connection using the example of 3 memory modules of different ratings. The first chip is 24LC02, the memory capacity is 256 bytes. The second chip is 24LC32, with a memory capacity of 4 kilobytes. And the third chip is 24LC512 with 64KB memory. Let's analyze the connection diagram, write and read selectively from different EEPROM modules. And then we will analyze the continuous recording of information, and the sketch will itself determine which chip from the series-connected ones needs to be recorded. And from which memory chip, in the future, you need to read.
For example, let's write pictures for an LED matrix into three series-connected EEPROM modules. And then we read them from memory and display them on the LED matrix of 16x16 addressable LEDs.
