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 ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The "4 digits 7-segment decoder VHDL" is a VHDL project designed to decode hexadecimal values and display them on 7-segment displays. Unlike a BCD (Binary-Coded Decimal) decoder (SN7447 IC for example ...

In a previous article, we explored the behavior of an LED diode as a small light source. We have seen how important a protection resistor is to light up this component. In this article, we will ...

Over on the [Behind The Code with Gerry] YouTube channel our hacker [Gerry] shows us how to emulate a 74LS48 BCD-to-7-segment decoder/driver using an Altera CPLD Logic Chip From 1998. This is very ...

Like most of his work, this tiny two-digit thermometer shows that [David Johnson-Davies] has a knack for projects that make efficient use of hardware. No pin is left unused between the DS18B20 ...

The exact time and date are obtained from the Network Time Protocol via Wi-Fi. For a smaller display, about 0.8-inch schematic diagram is very simple. Problems are with large segments, containing more ...
