While I have no problem putting a design together and writing code for free for what at least sounds like a paid job, a stripboard layout is not a small task and I've got several other projects I'm helping with right now, so I must beg off. It would cost a bit more, but you could design your own PCB with ExpressPCB easily and have them build you a few boards. Not as cheap as making a single board from a stripboard, but I don't imagine it will cost too much and it will add a level of professionalism to the end product. I'm happy to check your design if you go this route.It would be awesome to have a board layout and maybe plan of copper traces to remove, etc. as you did on my previous project !
If it wouldn't be too distracting, how about lighted test buttons? You could have them light up/flash when the appropriate switch is pressed. If you want more of a guarantee the MP3 is receiving a signal, you could either wire them in parallel with the MP3 channels and make sure the uC holds the signal for at least a full second so you "see" the pulse to the MP3 module or wire them to the unused outputs of the ULN2003. Tie the inputs together so when the MP3 channel is activated, the appropriate LED turns on.izon said:
Guess I could place the 3 LEDs going to the MP3 player where they are visible as it would be another indicator as to which room is calling for the help.
Shouldn't be. This is effectively going to be a dumb system. When powered, it will look to see if a button has been pressed. You can test this by plugging and unplugging the power multiple times to verify there are no errors before installation.izon said:
Is there a need to be concerned if power should go out in the building? They do have a standby generator that is automatically started up in this event but would that in any way
create a false triggering of this alarm system?
