how to burn atmega328p bootloader and power circuit

                       how to burn bootloader atmega328p

first you must upload the arduino isp programme  in to the arduino uno board like this

after uploading you must remove the power to arduino board and connect the wire like this
to board

arduino sonar system

                     Arduino sonar system 

in this project we need ultrasonic sensor 

and processing software for processing 

the processing software link is here
http://playground.arduino.cc/Interfacing/Processing
firs you must connect the arduino board to computer and upload the arduino code after you must open the processing software  and upload the processing code and run 

you must choose the serial port from processing code 


the processing code is here 

arduino ultrasonic sensor project

       Arduino ultrasonic sensor project 

the circuit is follow

in this project we program for when the distance <100cm the led is on 

and else led is off 

in this project we need 

• arduino board
• ultrasonic sensor
• led 

in this project the distance can show on the serial monitor 

the code is follow 

arduino LDR controller

                    Arduino LDR controller 


the circuit diagram here

FIRST YOU MUST GET THE VALUE FROM THE LDR READING FOR WHAT BRIGHTNESS
YOU WANT TO  CONTROL WITH THE SERIAL MONITOR 

the ldr value reading cord is here

arduino temperature sensor lm35

                                   Arduino temperature controller 

IN this project we need 

• arduino boad 
• lm35 sensor
• led

visual development tool for arduino

             

                 Visual development tool for Arduino

in this software easy to control we not need to programming its auto build the code

arduino toilet flusher

                  arduino toilet flusher

The circuit diagram follow 

in this project we use the 

• arduino boad
• ultrasonic sensor 
• servo motor 

in this project  

if some one came to the commode the ultrasonic sensor read and wait for 5s and after again scan the person who in the commode 

and after the arduino wait for flush the commode when the person leaving the commode 

arduino ir remote controller

                         arduino ir remote controller 

in this project we all so use library file 
visit to download http://j.gs/75JI

after add the library you must record the your own any remote button cords into the
HEX value

the code is there http://j.gs/75JK

arduino line following robot

                The simple arduino line following robot with LDR 


The circuit diagram is follow

The arduino code is follow 
http://j.gs/75CM


this project is tested by the proteus .

arduino keypad password controller

                      arduino keypad  password controller 

the circuit diagram is follow

 want 

1. arduino uno
2. arduino key pad 
3. led

arduino for proteus

                                               arduino for proteus 

first of all you must download the arduino proteus library from

http://j.gs/756O

then you open the library file and then copy it and past in on

C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\LIBRARY


after you can use it .

                 if you use the ultrasonic sensor you must upload the 
this hex file to ultrasonic in the proteus . the hex cord in hear 

http://j.gs/756R

and the project code is here http://j.gs/757D

if you have any problem please feedback
