This is a 3 Digit 7-segment display project that contains 3 x Common Cathode displays, current limiting resistors or each LED segment, 3 x PNP Transistor on each common cathode for multiplexing etc. The project works with 5V TTL signals but can be optimized for 3.3V operations by...

This project will help you to easily develop an Arduino compatible project that requires 4 x -7Segment 0.5″ displays. The project consists of an Atmega328 microcontroller, 4 x BC847 NPN transistors to drive the common cathode displays. All displays are used in multiplexing...

This project will help you to easily develop an Arduino compatible project that requires 3 x 7-Segment 0.5″ displays. These are common cathode displays that use multiplexed configuration, BC847 transistor drives 3 x common cathodes, all display segments are connected to the...

This is an Arduino compatible board for creating 2 Digit Display projects. The circuit operates with 5V DC, Connector CN1 is provided for bootloader programming and Arduino firmware upload. A new Atmega328 chip requires a bootloader and Arduino firmware programming, Connector CN1 helps...

Stephen Holdaway recently announced his project, a beautiful vintage VQB71 7-segment display based GPS Clock. Inspired by the fantastic appearance of the LEDs, Holdaway explains that the clock was built with a handful of vintage VQB 71 seven-segment LED displays and an u-box NEO-6M GPS...

An intelligent 7-Segment display based on Padauk MCU: Time for another project with a super-low-cost microcontroller. But what to design? Ever since seeing a project where a $0.03 MCU controls $40 worth of intelligent RGB LEDs, I have been wondering whether this is the right place to...

This is a giant digital clock, featuring four large LED displays that provide the time in a format you can read from the other side of the room. by David Johnson-Davies: This clock was inspired by some 2.3" one-digit 7-segment displays I saw on AliExpress [1]. I decided it would be fun...

I've seen a few other people experimenting with making custom LED displays using discrete LEDs so I thought I'd like to take my own stab at it. by sjm4306 @ hackaday.io TinyLED 7-Segment Displays -...
