BCD Counter Circuit
https://www.electronics-lab.com/article/bcd-counter-circuit/
BCD Counter Circuit A special digital counter called a BCD counter may count up to ten when a clock signal is supplied. As previously demonstrated, toggle T-type flip flops may function as separate divide-by-two counters. By joining many toggle flip-flops in a series chain, we may create a digital BCD counter that counts or shows […]
3 Digit Common Cathode 0.5″ – 7 Segment Display Module (Multiplexed)
https://www.electronics-lab.com/3-digit-common-cathode-0-5%e2%80%b3-7-segment-display-module-multiplexed/
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 reducing the current limiting resistors’ value. A […]

Vintage VQB 71 Seven-Segment LED Displays Make GPS Clock Both Brilliant and Attractive.
https://www.electronics-lab.com/vintage-vqb-71-seven-segment-led-displays-make-gps-clock-brilliant-attractive/
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 module. “There are only so many applications for a 7-segment […]
Intelligent 7-Segment Display using a low cost MCU
https://www.electronics-lab.com/intelligent-7-segment-display-using-low-cost-mcu/
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 use these devices. At this price point, doesn’t […]
Big digit 7-segment Clock using ATtiny3216
https://www.electronics-lab.com/big-digit-7-segment-clock-using-attiny3216/
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 to have a […]
