 // OVERVIEW SECTION ENDS
+=== Example Code
+// Describe what the example code is all about and add relevant code
+Reads the bit at the specified position and returns the value. In this example the binary representation of 6 is 0110, since `n=1` the value of the second bit from the right (which is 1 in this case) will be read and printed.

+  Serial.print(bitRead(x,n)); //reading the bit at position n and printing the value
+}

+
+[float]
+=== Notes and Warnings
+The indexing of the rightmost bit starts from 0, so `n=1` reads the second bit from the right.
 
+Both `x` and `n` must be integer type.
