Writing and Reading to a config file.

Hi,

I'm working on a project that control the inside of a terrarium. I've got a Bluetooth Arduino that and a series of solid state relays that control light, fans etc.

I'm trying to tackle a a user friendly software interface that will allow a person to set a schedule for the relays. Right now I can reprogram everything from the IDE. But my goal is to have the arduino write a config file somewhere in memory that sets the timing for the triggers of the relays.

Any thoughts or pointers on how to best do this. I know that there are things like DOS on a chip etc.. Just looking for good examples from the community.

Thanks!
Mark

My advice would be to use the eeprom to permanently store this information. Then when you want to change it you can do it from the console or run a program on the PC with a fancy front end to set these eprom values.

Easy with an eeprom (see tutorial on the i2c eeprom) and the DB.h library provided for it.
