Passenger Metering

In this tutorial we see how we can build a easily monitor how many passengers went IN or OUT.

Depending on the direction of travel, the device counts the number of people left inside. Each passage in front of the device is signaled by a beep. The D13 pin output can also be used for various operating purposes.

1. Arduino nano board
2. 2x HC-SR04 ultrasonic sensors
3. Oled display
4. push button
5. 1k resistor
6. buzzer module
7. Visuino software

Make the connections of the components according to the diagram below( audio buzzer is optional part)

the code is automatically generated by Visuino, but it is recommended to build one according to the tutorial in the video.

The video describes an entire tutorial on how to do this project.

Visuino software is free version, download here: https://www.visuino.com/download

At this point we connect the components according to the diagram.

Power up the device and press the reset button. At this point the project is complete and the device is ready for operation.
