i wanted to know about your experiences with the arduino and applications that should run over a long time. is there anything to be taken care of? for example something that executes a function every 86 400 000ms, which is one day. are there any limits concering running time? i read the archives about power managment and suggested power supplies, so i'm only missing information related to coding. i've also studied this post concerning resetting the internal timer variable - is this all that needs to be done?
