Build a Bidirectional Visitor Counter using Arduino and IR sensors to track entry and exit movements with real-time counting on an LCD display. This step-by-step guide covers circuit design, hardware ...

Monitor traffic with style using the Arduino Vehicle Counter. This project leverages an infrared sensor and an LCD screen to accurately count passing vehicles. Whether for traffic analysis, ...

Circuit Diagram for Arduino Accelerometer Step Counter is given below. In this circuit, we are interfacing with Arduino Nano with ADXL335 Accelerometer. X, Y, and Z pins of the accelerometer are ...

I made this Arduino 8 bit binary led counter as a solution for one member from Arduino forum. He asked if somebody can make a project that displays a decimal number in 8 bit binary format using 8 leds ...

So the width is given by W= d-(d1+d2) Based on the width the vehicles are classified, Once the vehicle is classified the counting of vehicle is done and it is saved in SD card. For the demonstration ...

Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter from 0 to 9. The whole circuit can ...
