Hello All,
I am trying to design a battery operated device that can wait a duration of time measured in weeks up to months and then activate a piezo buzzer for a few seconds (between 3 and 10 seconds) then wait again for the same or a similar duration of time and do it all over again until the battery is run down. The thickness of the board and components need to be able to fit through a slit approximately 7mm wide (possibly a few mm thicker would be fine).
I've looked at 555 / 4017 options and while I'm open to exploring it further it didn't seem like I'd be able to get the components I needed to fit into the 7mm width I'm looking for. I'd be happy to use a microcontroller but I know absolutely nothing about them except what I learned in the last 24 hours browsing the web, not that I know much about circuit design in general.
So as far as my knowledge of microcontrollers go I like the TI msp430 series for their low power features. I would appreciate any code for any of the TI msp430 low power chips that could be programmed to do what I needed. Any ideas of implementation are greatly appreciated.
Also, it is important to note that I only need reliability to the day, the timing could be consistently off by hours and it wouldn't be a big deal, even inconsistencies of around a day would work.
Thanks,
Simon
