Corner Warning System / Warning device

Corner Warning System

When walking around the corner, we will be sometimes shocked by the people coming from the other side, and what’s worse, we will even clash into them and get hurt.
This project provides a corner warning system, which connects the piezoelectric device on the ground to the LED warning device on the wall of the other side, to signal a message of warning if someone from the other side is coming. Therefore, it will avoid causing embarrassing or dangerous situation.
