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
