MUSICAL DOOR BELL

                          MUSICAL DOOR BELL


                     The musical door bell is the circuit in which the transistor which make an melody sound in it.It has the oscillator in it which has the capability of producing 14 indidual tones in it.The BT66/UM66 transistor is the melody sound generator circuit.

Components Required:



                   1)UM66/BT66 Transistor
                   2)Speaker/Buzzer
                   3)Dc Supply
                   4)Connecting Wires

Circuit Diagram:


Procedure:


          Take the UM66/BT66 Transistor and connect it to the breadboard,and connect the first pin of transistor to Negative and next connect 2nd pin to positive and connect the 3rd pin of transistor to one end of speaker/buzzer.Connect another end of speaker/buzzer to negative.Now connect the switch between the positive terminal and to the circuit.When the switch is on the Circuit works.

CHECK HOW THE CIRCUIT WORKS:

Ice Bergs Melt due to Carbon dioxide

Ice Bergs Melt due to Carbon dioxide What is CO2?                                  CO2 which is expanded has Carbon dioxide . The CO2 in atmosphere is 0.04 and present in Earth Atmosphere. The CO2 is basically an Green House Gas which plays in important role in Maintaining Earth Average Temperature of 57 degrees Fahrenheit . The CO2 is basically an heat trapping effective green house gas. It does not trap all gas molecule on IR radiations and it also remits the IR radiations during night where other else earth average temperature will be 0 degrees Fahrenheit . Any how not only CO2 all green house gases plays an important role in it. How CO2 produced?                              CO2 is given naturally by respiration and deforestation and Main r...
