&&

[Boolean Operators]

Description

Logical AND results in true only if both operands are true.

Example Code

This operator can be used inside the condition of an if statement.

if (digitalRead(2) == HIGH && digitalRead(3) == HIGH) { // if BOTH the switches read HIGH
  // statements
}

Tip

Make sure you don’t mistake the boolean AND operator, && (double ampersand) for the bitwise AND operator & (single ampersand). They are entirely different beasts.
