Hi Guys,
I'm designing a product at the moment and developing the circuitry with an arduino.
The basics of the concept is an alarm with a key pad deactivation..
A 4 number code is set, then the device recalls this code every time it is turned on
This code is required to be changeable, but it will not happen often.
Basically my issue is that i do not know what sort of micro chip will be needed to hold this information or if some kind of component array can be cheaply used to do the same job.
I'm not at all clued up on this stuff, but i'm trying hard!
It would be great to hear what you guys think is the best way to go about this.
