animated led sign board without programming - electronic sign board
This is an electronic engineering without programming or micro-controleryou can do your own custom text led Star Mining with this circutin project I use the cable resistance IC 74 ls164 and IC 555 animation.
You can make led board with 8 letters in my project "welcome", it is 7 letters word.
All components of the project can be obtained via video link-

I made 7 letter words in my project "welcome. You can use this circuit to make an led sing board for your own custom words, with up to 8 letters of words connected to other etching (per letter)
The negative pin is connected to the collection pin of the transistor and the positive pin is connected to the 680 ohm resistor & if your word is large, all resistors change to 12 volts positive & you use more resistors in each letter below 680 ohms.
For larger signage, you can use a separate power supply for the LED board. IC -
74 ls164 & IC 555 operates at 5 v voltage, so here I used a 5 voltage regulator IC 7805 potentiometer 100 K connected to the timer IC 555 pin 6 & 7.
You can use this potentiometer 8-piece 54b transistor for driving LEDs to control the animation speed & another transistor 54b for resetting pinnow use the circuit diagram to make the circuit to connect the transistor collector pin to the led board for each letter vero board with negative pin, 12 volts are directly connected to the led board, where all 680 ohm resistors are connected.
Power it with a 12 volt 1 Amp DC power adapter.

In today’s fast-paced business and education landscapes, clinging to outdated technology like projectors, traditional whiteboards, or non-interactive displays isn’t just inefficient—it’s a financial drain. Studies show that organizations waste up to 15% of their annual IT budgets maintaining legacy systems, while struggling with compatibility issues, energy inefficiency, and productivity bottlenecks.
The solution? Interactive Flat Panels (IFPs). These smart displays aren’t just flashy upgrades—they’re proven cost-cutters. Here’s how to slash your operational expenses by 40% or more in just three actionable steps.
