LED bulb with battery vs microcontroller

How to use LED bulb with battery?

The LED bulb using for vehicles, home or office use streetlights also use, we go little bit normal using of LED bulb or DC motor with 1.5v to 5volts by using other components like 8051 Microcontroller IC.

We learn in school about True or False in Math's, like Conjunction, Disjunction etc., one means True and zero means False. In computer language is 1 and 0, called as bits, 4 bits is nibble and 8 bits is one byte.

Green LED Bulb Glowing - 9v battery

To easily understand binary to machinery language such as Octal or Hexadecimal binary codes like 1111 4bits is "F" 0000 4 bits is "0".

The same concept in Microcontroller 8051 have four 8-bit ports are available, you can do any task by sing these four ports, if you want blink light take 4 LED bulb red color and 4 LED bulb green color or DC motor using H-bridge IC to control from Microcontroller 8051. Try to blink alternate you need to write program in Embedded C code, by using software like KEIL C51 software. From basic for beginners can do first take one Green LED and connect to battery like 1.5v to 9volts, 1.5 volts is enough for Green LED to glow the bulb.

DC motor small - 9v battery

In circuit board like 8051 Development board use LED light to indicate power is ON or OFF. Using microcontroller 8051 have four 8-bit ports, take Port 1 have 8-bit pins, you can write a code to blink the LED lights, you need 1k resistor to give life span for LED bulb.

In Embedded C code or program have to write as #include <Regx51.h> is a header file for microcontroller 8051, presently in Market good microcontroller is AT89S52 is enough for your project kit in Embedded system.

 

For example:

#include <Regx52.h>

Sbit P1^0;

Sbit P1^1;

upto Sbit P1^7;

you can use some Delay function as int i, j (i=0; i<=1275; i++) {J=0; j<1000; j++)}

 

int main ()

while {

P1=0xff /*to ON to glow blub

Delay (1000);

P1=0x00 /*to OFF the blub

Delay (1000);

}

The above Embedded C code or program is a sample for understanding the concept of Microcontroller 8051 program fetching input and output pins connecting to LED bulb with 1k resistor.

}

Conclusion:

As per understanding the concept of LED glow the bulb with 9v battery but the life span is in minutes or second why because power is too high, you can use 1.5v battery is enough for small LED bulbs. You can do experiment on 8051 microcontroller IC, how it will work with Embedded C code or program. To understand the Memory in microcontroller like General purpose, bit addressable, registers bank0, bank1, bank2 to temporary use the code or memory.

Rigging 3d character:

The rigging is a heavy duty of by checking the 3d character modeling and texturing after that preparing joints to boy size putting in center through the viewpoint of axis x, y and z axis. Need to concentrate while doing the rigging which have axis joints by rotate the axis, to move the hands and legs of entire body system. All joints have different axis need to have direction Y-axis in legs joints, can take IK handles simple way to walk the body with legs, like wise same with hands, from shoulder to fingers or pan. Don't forget to give names for hands and legs it's very important.

When opening file of .OBJ to import file, only available modeling of 3d character by select and press key "3" to smooth, then you need to develop the rigging and controls if you have interested you can do it. Do practice two to three times, then only you can achieve the task of rigging.

3d character wire frame - image-3

Animation 3d character:

The animation is a part of action by one object to another object communication, in animation have or have 3d character modeling with rigging with control circles, by controls you can animate by pressing in time frames from 1 to 120 frames its around 5 seconds, one action like legs doing walk by press key "S", select time frame 1 movement to 4 then press key "S" one action is over, in legs. 

Conclusion:

As per my understanding is about the animation making with the help of Graphic editing is showing the movement of axis green, red and yellow its Y, X and Z-axis. By checking which axis to move the object or character can identify the color as Red, Yellow and Green. To check Move the object then press "W" and see the directions.

Proteus software LED with 8051

How to use Proteus software for embedded systems?

The Proteus software is very useful in Embedded system, without hardware, you can do project testing with library components using in Proteus software.

In this software have so many components to use electronics parts available to do the test project without wasting time on hardware part.

Microcontroller-Proteus software-image-1

Let's start to do project in Proteus software, open new project gives file name or project name then open the Proteus software application, here you need to check the particular components to interface with 8051, like as resistor, capacitor, diode, transistors, regulator so on...

For example, project name is LED blink interface with 8051 microcontrollers. Here you need embedded c code or program on LED on and off with delay function.

Sample Embedded LED blink C Code:

#include<reg52.h> 

Sbit LED = P2^0;    // connect Port2.0 in 8-bit i/o pin microcontroller LED pin

void Delay(void);          

void main (void)

{

   while(1)            

    {

        LED = 0;            // LED OFF

        Delay(50);

        LED = 1;            // LED ON

        Delay(50);

    }

}

void Delay(void)

{

    int j;

    int i;

    for(i=0;i<10;i++)     //Delay function

    {

        for(j=0;j<2000;j++)

        {

        }

    }

The above embedded c code must use in Keil C51 software, already we have posted on Keil C51 Software, how to use the C code in software. After settings in Keil software you can rebuild button in Keil software, there shows error and warnings. if you got error you need to rectify, the above code is successful execute in microcontroller.

In Keil software must enable Hex file and give crystal frequency is 11.0592Mhz.

Proteus software microcontroller settings

Then, after generating click on rebuild in Keil software, you will get Hex with file name. Now, open Proteus software, click on components library search microcontroller and LED just connect respective pins from Embedded C program.

Microcontroller with LED blink green

Double click on microcontroller you will get pop up give crystal oscillator and hex file, then click OK. then after click play button, now see LED will blink with some delay function.

Conclusion:

As per my understanding, is how to do program in Embedded c by using pins configuration design in Microcontroller, some have delay on Timer, counter, Interrupt. Just simple edit the code with Relay of "LED" to Relay, if you use relay, you can change the name "Relay". connection between microcontroller to Relay interface. Take single channel 5v 10amp Relay to use in project.

Install OS on a USB Pen Drive

How to create Windows OS in USB pen drive?

The windows created is from windows 98 to till windows 11, lot of changes happened in operating system, some has using server runs with "windows server 2003", like this version came, some are using Linux operating system, it's under networking or any higher people use.

Installation OS in USB pen drive:

The USB pen drive using Operating system windows 7, 8, 10 and 11 version, which version you want to use you can, for example we took version 10 windows, now we use to USB pen drive, just plug into the USB port in PC or Laptop, then after open rufus USB software, in rufus install the drivers in windows 10 then after insert pen drive 8GB (Giga byte) or 16GB or 32GB you can use this pen drives as per your requirement.

Rufus software install OS image-1

After selected the pen drive 32GB (Giga byte) for operating system to insert files by using rufus software after opened the rufus. it will detect the USB pen drive data, like as how much Giga Byte and it should empty, if have data, it will message or popup to you as "in this driver have files" if you want to delete and continue, if yes, press ok. here stared will do format and select bootable disk iso file of windows 10 select iso then press start, it will take to 15 minutes or half an hour to complete the operating system files.

Rufus software ISO image-2

Don't forget to select GPI at partition scheme, it will nicely work normal computer or high computer to format and install lates OS in computer. if you want speed then you need to update storage device like NVME M.2 SSD. if this SSD have, it will work speed in computer.

BIOS Setup in Computer:

Before formatting, take back up the data from your Hard disk or SSD, then after do formatting the OS. first insert the "USB pen drive windows 10" to pc or laptop then ON computer or laptop immediately press key DEL from keyboard, then you will appear BIOS setup select Boot option there have option as "First Boot Device" and "Second boot device", select first boot device as "USB pen drive windows 10" then press any key from keyboard then start the process to format OS installation into your computer PC or Laptop.

BIOS setup in Computer settings DEL

Conclusion:

As per my suggestion on OS installation is using USB pen drive to format OS in PC or Laptop, rufus 32bit or 64bit software, then only consider respective operating systems can select, then only do format. remember take backup into alternate pen drive or hard disk.
