Saving LED Configurations to Arduino Using EEPROM

~ 8bitbuddhist ~ 2 Comments

While working on the next release of PixelMaestro, I came across a problem of storing long-term data on an Arduino. I have a system in place where configuration changes are sent to an Arduino over USB as byte arrays, and as the Arduino reads the array it applies the changes. The problem is those changes disappear as soon as you restart the device. How, then, does one store persistent data without having to add an SD card or extra memory? Enter EEPROM.

A few months ago, I decided to buy an Arduino. For those who are unfamiliar, an Arduino is a small programmable computer typically used to power a specific application such as a smoke detector, medical device, watch, household appliance, or automobile engine. My reasons for buying an Arduino were twofold: I wanted to learn how small, embedded computers were being used to power our everyday lives, and I wanted to learn more about the Maker’s Movement. While this post focuses on the first reason, you can learn more about the Maker’s Movement through a variety of resources including Make Magazine and Wikipedia.
