Audio amplifier circuit

Audio amplifier circuit

This is an simple audio amplification circuit (mono/stereo)

  Things needed for this project

   *  9v battery 

   *  1000mf 16v capacitor
   *  220mf 16v capacitor

   *  10mf 63v capacitor

   *  breadboard

   *  LM386  IC

   *  speaker  (i used 3ohm 4w spk)

   *  jumper wire's

make the connections according to the below 

breadboard  diagram

    *  Just remove the insulation of the aux stereo

       cable and  connect the red wire (left) or white

        wire (right) as positive input and black as

        the ground. (ground is common for both red

        and white wire) 

     

     NOTE: the red wire is for left audio input  

                (positive ),   the white wire is 

              for right audio input (positive)

                 

               

                                                  

                               

                                                  

                    

   The above circuit is for mono amplification , for
    stereo amplification two circuits has to be made
     in the similar way ( one circuit for left speaker
     and other for right speaker ). 
    
      I made this circuit in the pcb by soldering the 
    components in it.......
