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 ...

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 ...

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 ...

Hackaday editors Elliot Williams and Mike Szczys go down the rabbit hole of hacky hacks. A talented group of radio amateurs have been recording and decoding the messages from Tianwen-1, the Mars probe ...

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 ...
