My Final Project
Description of the project
he vest contains LED lights and vibrators ,These vibrators activate when a person gets close to it.
Sketch
- Detects nearby presence from behind (proximity sensor).
- If someone gets too close, it vibrates lightly.
- It does not turn on visible LEDs or make noise, only when activated with a button.

Objective
This vest helps people in their safety by alerting them when someone is nearby.
What does it do?
I am going to make a vest with the following features:
- The vest will protect people at night.
- The vest will be very practical because it will be easy to put on and take off.
- The vest will have LED lights and vibration.
Who's done what beforehand?
I reviewed other related projects and found some that inspire mine.
In my research, I found a mirror with several features, one of which is that it contains a motion sensor, and when it detects movement, it lights up the mirror.
Another idea I found was this type of vest that protects people at night because it has integrated LED lights that make them visible.
What sources did you use?
