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 ...

As the code for the Nano was derived from the GPSDO code, it is again written in C using the Arduino IDE. The frequency counter code is basically driven by the 1PPS interrupt.

[Todd Harrison] really has our number. Like him, we don’t want to spend money when we don’t have to, and hacking our own solutions is a lot more fun anyway. This time around he’s … ...

This project demonstrates how to create an 8-bit binary counter using the 74HC595 shift register, 8 LEDs, and an Arduino. The binary counter displays values from 0 to 255 in binary, with each LED ...

Arduino 7-Segment Display Counter This project demonstrates how to drive a 7-segment display using an Arduino. The display counts from 0 to 9, with each digit displayed for one second. Each segment (A ...

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 ...

The Arduino fetches the time from a DS1302 RTC module and splits the result up into four-digit time. Code-wise, each digit gets its own array, which stores the active and inactive positions for ...

Computer engineer Thiery Guennou based in France has created a new Arduino compatible precision frequency counter 5 or 120 MHz. The inspiration behind the Arduino board was to build an open, very ...

ArduSat is an Arduino-powered satellite being funded through kickstarter to foster open satellite access and the collection of data from sensors in space. It will be able to run code for up to a ...
