LED CUBE

Hi Friends .just think about led's .led s are amaizing if we use perfectly.lets make led cubes we can make 2*2*2 ,3*3*3,4*4*4.......etc.we can controland add effects on led cubes by using arduino,8051.. etc.but we need to know how to make led cubes .here iam going to explain how to make 2*2*2,3*3*3 led cubes from this you can understand how to make higher cubes.i prefer arduino for controlling led .because it is very simple to use and code .i will discus the cording parts in next post

1 -2*2*2

components

1-8 led

2-resisters to decreas voltage  

    the circuit is shown below

       

                      SOUND SENSOR FOR ARDUINO

 

Hii friends today we are going to make a simple sound sensor module for arduino .It can also used singly for other projects or in combined with microcontroller s.The main combonent is ICNE555,electric MIC

COMPONENTS LIST

1)R1-10k

2)R2-1M

3)R3-15k

4)R4-1k

5)R5-100 ohm

6)C1,C3-1000pf

7)C2-10uf

8)Q1-BC547

9)U1-ICNE555

10)MIC

SENSOR FOR LINE FOLLOWER ROBOTE

       SENSOR FOR LINE FOLLOWER ROBOT

Haiii friends lets think about a line following robot.The important part of a line following robot is the sensor.no of sensors are avilable in online and offline market but its costly here we are making very simbl sensor but very high sensing capacity.

we need some simbl components

1-IC LM358

2-RESISTER,100ohm,10k

3-preset-10k

4-led

5-IR LED

6--IR RECIVER(PHOTO DIODE)

The circuit shown below .next time iam come with LINE FOLLOWING ROBOT

SIMPLE MUSIC GENERATOR

            HOW TO MAKE A SIMPLE MUSIC GENERATOR
It is very simple to make a music generator.We want only few components for making
music.
1-Function generator
2-amplifire
3-speaker
4-voltage source
Here we are using the most basic function generator IC UM66.This generator can make
some basic music signal which is connected to a amplifire through a resister 220 ohm
.Here we use the basic amplifire TRANSISTOR BC548.The out pin (_) of ic is connected
base of the transistor and the amplified signal is taken from collector and connected
to speaker.
COMPONENTS
1-IC UM66
2-TRANSISTOR BC548
3-RESISTOR 220 ohm
4-speaker
5-BATTERY 3V
