Animated LED sign board without programming

It is an electronic project without programming or any micro controller
you can make your own customized word's led sing board using this circuit

in this project I have used shift resistor IC 74ls164 and IC 555 for animation.
you can make led board with 8  letter words

I make in my project "WELCOME " word it is 7 letter word.

All components of this project are available at https://lcsc.com

I will provide also buying link of parts witch I used.


Parts list -

LED - 5mm    Buy

IC - 555              Buy
IC - 7805            Buy
IC - 74LS164     Buy

IC - ic base 8 pin   Buy
             14 pin       Buy

Diode - 1N4148      Buy
Transistor bc547 b
                or 548 b  Buy
Capacitor - 0.01     Buy
            10uf/50v    Buy

Potentiometer 100K Buy
Resistor - 10K           Buy
           1K                 Buy
           33K               Buy
          680E              Buy
DC socket                Buy

vero board               Buy

1. Making LED board


all led's positive & negative pins are connected with etch other (per letter)
negative pins are goes to collector pin of transistor
Positive pins are connected with 680 ohm resistor & all  resistors goes to 12 volt positive


2 .Making controller board


IC - 74LS164 & IC 555 runs on 5v volt so I used here a 5 voltage regulator IC 7805

Potentiometer 100K connected to pin 6&7 of timer IC 555.you can control animation speed using this Potentiometer

8 piece 547b used for drive the leds & another one transistor 547b for reset pin
Circuit diagram of LED controller board


now join LED board to LED controller board
all transistor collector pin goes to LED's negative pins

Connection & wiring of 24 v electric bi -cycle By Techno review 85

Image
In this post I want to describe How to connect all parts like brushed motor, throttle brake light, ignition switch via controller It is very easy to wiring e bike parts About Parts you need to make  & all details about electric bi - cycle Click here  You have to use a motor controller ( in my bike I used 24 volt controller) There are lots of wires coming out form the controller .we have to connect those wires to motor,battery,throttle,break ( optional) & ignition switch It is full wiring diagram of ebike Some important  Use 4mm wire to connect battery To use LED as indicator must use a resistor with LED For ignition switch you can use Mofet ignition switch Use good quality parts & wire If you do not have much knowledge about electronics , then take a professional help For details of new version electric bicycle click here

Raspberry pi 3.5 inch LCD screen setup & install driver

Image
This tutorial for beginner raspberry pi user .It is very easy way to install driver for 3.5 inch touchscreen LCD. Before install driver You need A Raspberry pi 3B with raspbian OS because this Lcd screen works with only raspbian OS 1.First Download Txt file from here Save it to your raspberry pi desktop 2.Make sure you have internet connection on your Raspi 3.copy upper part of text from downloaded text file & paste it to terminal emulator Now driver will install & Lcd turn on but HDMI will turn off LCD & touch is working after automatic restart  4.To turn off Lcd & active HDMI ,copy lower part text from Downloaded text file paste it to terminal emulator .Now HDMI will active & Lcd turn off This is full details video for installation driver
