How to generate a beep sound in a watch ? Answered
I'm working on an electronic design project : Smart Watch
this watch worn by clients suffering from early stages of Alzheimer disease will play a role so that it guides the patient back to his/her house .
We pre-defined a distance boundary that the client will not exceed (speedometer). I want to know if there is a device (sensor) that should be integrated in the watch so that it generates or creates beep sound (or vibrations) once the client crossed or approaches the Limit distance boundary ( something similar to the beep sound in the car system when it approaches an obstacle ). And , if it is possible ,any ideas or hints on how to implement it on the watch ? Thank you in advance , and if you need more information please let me know :)
