+#OBSERVATIONS      
+                  1.  For sufficiently large value of R2 frequency only depends upon the value of R1 and C1.
+                  2.  More the value of resistance(R2) more quickly it reaches the stable frequency value.
+                  3.  Frequency is given by f=1/(0.7*2*R1*C1) .
+                  4.  Now we can attach potentiometer in place of R1 and use it as a rheostat and observe how the frequency changes.
+
+NOTE : The above observations are for 555 oscillator with 50% duty cycle.
+
+Requied components- Two resistors, two capacitors, breadboard, battery, 555, LED.
+
+#Steps         
+         1. Connect terminal1 of R1 to trigger and terminal2 to output.
+         2. Connect terminal1 of R1 and threshold to terminal1 of R2.
+         3. Connect terminal2 of R2 to reset, power and positive terminal of the battery.
+         4. Connect ground to negative terminal of the battery.
+         5. Connect terminal1 of R2 to terminal1 of C1 and connect terminal2 of C1 to ground and terminal1 of C2.
+         6. Connect terminal2 of C2 to control voltage.
+         7. Finally connect anode of LED to output and cathode to ground.
