Story

This system represents a parking lot. Only three slots are considered for Simplification.

The system consists of Arduino Uno, Ethernet Shield, Blynk App, and IR sensors. Sensors are used to detect the presence of a Vehicle. As soon as a vehicle is detected in a particular slot and the corresponding led on the App goes high.

The Blynk app can be downloaded from the play store as well as the IOS.
