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.

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, ...

With Christmas around the corner, you may be wondering about what to gift yourself. Don’t worry. We’ll help you to make the perfect gift for yourself. Its a blog hit counter that rings a bell whenever ...

This project uses an arduino to read the values of two potentiometers to display a number on a LCD screen, ranging from 0-255. One potenitometer increments the counter by multiples of 1, and the other ...

Arduino Frequency Counter Code Explanation: Code for this frequency measurement using arduino is quite simple and easily understandable.Here we are explaining the pulseIn function which is mainly ...

Wireless Visitors Counter Parts List. After successful wireless transmission, the pulses arrive on the data pins of the HT12D decoder on the receiver side. The two data pins of the HT12D are connected ...

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. ... Now lets see the schematic and how I’ve ...

Sure, parts counting scales are a thing, but that’s hardly a walk-away solution. So with the help of some laser-cut gears and a couple of steppers, [Ryan] built a pretty capable little parts ...
