Pic's I find are fascinating little devices......debugging you software is a challenge too........
Dependant on how confident you are in your abilites, perhaps an alarm is may be a bit too ambitious......may be not. .. :lol:
do you have access to a pic programmer? is my first question.......
and apart form the alarm, do you have any other ideas in mind?
If you decide the alarm is what you wish to pursue, then can you give a little more information on it, like what you want it to do, how is the alarm going to be armed/activated etc.........
