Have you ever noticed how shopping malls, parking lots, or event venues seem to track the number of people or cars present inside? You might think they use an AI camera to count them, but in reality, ...

This Arduino Coin Counter project utilizes commonly available components to create a user-friendly coin counting system. By employing an Arduino Uno, ESP8266, or ESP32 micro controller, along with an ...

In this project we are going to work on an innovative arduino project idea, where we can count the paper currency notes and calculate their amount, by sensing the paper currency using Color Sensor and ...

This project demonstrates an Arduino-based counter using a 4-digit 7 segment display. The counter counts from 0 to 9999 and displays the current value on the 7 segment display. The Arduino 4-Digit 7 ...

This article presents the implementation of an Arduino ... in this project—one at the entry gate and one at the exit gate. The circuit diagrams of the transmitter and receiver are shown in Fig. 5 and ...

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

So [Todd] has set out to build an Arduino frequency counter for a Kenwood TS-520S HF ham radio. This post (and the video found after the break) doesn’t cover the entire project. It’s rather ...

Arduino Lint is an easy-to-use, yet powerful, command line tool, focusing on the structure, metadata, and configuration of Arduino projects, rather than the code itself. This tool is designed to ...
