Bi-Directional Visitor Counter Using Single Ultrasonic Sensor With LCD on TinkerCad

Often we see visitor counters at the stadium, mall, offices, classrooms etc. Today we are here with a project with bidirectional visitor counter by using Arduino Uno. It is a very interesting project for hobbyists and students for fun as well as learning.
The project of Digital visitor counter is based on the interfacing of some components such as sensors, motors etc. with Arduino microcontroller. This counter can count people in both directions. This circuit can be used to count the number of persons entering a hall/mall/home/office in the entrance gate and it can count the number of persons leaving the hall by decrementing the count at the same gate or exit gate and it depends upon sensor placement in mall/hall. It can also be used at gates of parking areas and other public places.”
