VOLTAGE CONVERTER

                                     VOLTAGE   CONVERTER
HI Frndssss........

Today  i m goning to make voltage converter ......

in this project we learn how to convert ac to dc and 220v to2v
view details here.....


COMPONENT     LIST:-
1.  Transformer(12  0  12)
2.  Diodes -4
3.  capacitor 1000uf ,500uf
4. lm7805
5. resistance 330 ohm
6. led 2v

CIRCUIT DIAGRAM:-



Working Principle:-
 Frist we discuss about how to convert ac to dc  ?
here we have 4 diodes we make bridge rectifier  . the block diagram of this circuit is given below :-
ac 220v is connect to tranformer . which convert it into 12 v  here we connect capacitor 1000uf it store charge and stop fluctuation of volt . then it we connect a lm7805 which is voltage regulator  it convert 12 volt  in 5 volt then it a capacitor 500uf  and 330 ohm resistance connect led .here circuit is fully completed.

auomatic wash basine

Hiii
frndzzz......

Now i m goning to make small project which is based on ic 555 . this project name is automatic wash basine...
                                        
                                        
                                            auomatic wash basine



component name    1 . ic 555  ( Timer)
                                2. relays (12v)
                                 3. lm 7805
                                  4. capacitor 
                                  5.tansistor
                                 6. light depending resistance (ldr)
                                 7.potentiometer (10k)
                                 8. laser light 
                                 9.cooler moter and some pipe....


princpal:
 L DR  is a light depending resistance which  resistance is dependent  upon light when the light fall on it its resistance increase and voice-versa . in this circuit we use ic 555 which is a timer  so our out put in the form in  digital (0,1). relays is used to switching circuit .lm7805 for regulated voltage  5 v for  my ics and other  component........ when laser light fall in ldr its resistivity increase  then our put in the form of 0 and the light is distrubed by us resistance is less so in the out put we get  1 in pic ...............
