# Arduino Bitwise Operators - Arduino

## What is Arduino Bitwise Operators?

Assume variable A holds 10 and variable B holds 20 then −

 Operator name Operator simple Description Example and & Binary AND Operator copies a bit to the result if it exists in both operands. (A & B) will give 12 which is 0000 1100 or | Binary OR Operator copies a bit if it exists in either operand (A | B) will give 61 which is 0011 1101 xor ^ Binary XOR Operator copies the bit if it is set in one operand but not both. (A ^ B) will give 49 which is 0011 0001 not ~ Binary Ones Complement Operator is unary and has the effect of 'flipping' bits. (~A ) will give -60 which is 1100 0011 shift left << Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by the right operand. A << 2 will give 240 which is 1111 0000 shift right >> Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by the right operand. A >> 2 will give 15 which is 0000 1111
