I need a wristband that emits vibrations until you wake up.
The idea is to awaken the user without the need to issue any sound.
The bracelet would be composed of lightweight materials so as not to disturb the user during sleep.
The user configures the time that will awaken your bracelet as is normally done in watches.
configuration hours 0-24 hours
DISPLAY FORMAT: HH: MM
Then comes other questions:
Batteries commonly used in watches, would be appropriate, or consume rapidly with vibration emissions?
Suggestions are welcome for this.
