[line-3, body-2]
+ Started</br> 29th Nov 2024
+ Problem Statement
+ I have told to make a smart watch for ladies protection , which sends a sos message containing the current locatio to the parrent and the police in the following senarios
  - A button is pressed
  - Heart rate is unusual that normal and "HELP" command is detected
 **Requirements**
- Heart Beat -> to Sense
- SOS Switch
- Voice Detection
+ First Meating</br> 30th Nov 02-12-2024
+ Initial requirements
+ - It should have a sos button and when that is pressed
> it the microcontroller will send the watches location to police and parents
- To facilitate failsafe , the watch also senses heart rate and if the heart rate is above some threshold it will also send  location to parents and the police
- Continuesly monitor for the command **HELP!** if help is found do the sos thing
