This project is an object/person detection counter built with an Arduino Uno, an IR sensor, and a 16x2 LCD display. Whenever an object (e.g., a person walking past or a hand wave) interrupts the IR ...

The aim of this project is to develop a circuit that can count the number of people entering and exiting a room using two Infrared (IR) sensors connected to an Arduino UNO. This bidirectional counter ...

The experiment is for switching an acoustic sounder as a rain alarm after a predetermine time. It may, however, be tinkered for a number of other applications. Needless to say, this is a simple ...
