+/* PushRotate
+  by K.Abhijeet
+  This example code rotates the servo motor clockwise or anti-clockwise as per button pressed.
+
+  Circuit:-
+    Arduino Uno
+    Micro Servo Motor connected at pin 9
+    push button1 between pin 6 and VCC with 220 Ohm pull-down resistor(rotate anti-clockwise)
+    push button2 between pin 7 and VCC with 220 Ohm pull-down resistor(rotate clockwise)
