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