5v 1 amp DC POWER SUPPLY

5 VOLT 1 AMP DC POWER SUPPLY 

             IT IS very easy and cheap 5v supply for microcontroller or other digital electronic circuits . it can use to charge the mobile phone . 2nd diagram is useful for mobile charging it can connect with car battery and out put will charge the mobile 

STREET LIGHT

                                AUTOMATIC LIGHT SWITCH 

IT is very useful circuit for home or building light . some time you forget to turn off light in morning and when you come home in evening then you see that light is on . so that circuit will turn on light in night and turn off in day time

 AUTOMATIC CONTROL THE GARDEN WATERING SYSTEM

I MADE A SIMPLE COMPUTER USING 8051 MICROCONTROLLER . THERE ARE TWO MODES OF THAT DEVICE AUTO AND MANUAL . 

THIS IS WATER TEST SECTION . IT TELL WHICH SIDE OF GARDEN IS DRY OR WET .

PUMP AND LIGHT CAN BE CONTROL AUTOMATICALLY OR OWN SELF TWO OPTIONS FOR LIGHT AND PUMP CONTROL  

THIS IS SIDE VIEW WHERE POWER PIN AND SENSOR IS CONNECTED
