or || 称为逻辑OR运算符。 如果两个操作数中的任何一个非零,则条件变为真。 (A || B)是真的 not ! 称为逻辑非运算符。 用于反转其操作数的逻辑状态。 如果条件为真,则Logical NOT运算符将为false。 !(A && B)是假的 按位运算符 (Bitwise Operators) ...

The “!=” operator in Arduino code means “not equal to.” This is a comparison operator used to evaluate if two values are not the same. In an Arduino program, this operator can be used to check whether a variable has a certain value or not. For example, you could compare two numb...
These operators are used to compare the values of the operand. The types of comparisons performed are equal, not equal, less than, greater than, and many more. These comparison operators return a boolean value (True/False). 3. Logical Operators These operators help make the decision based on...

A logical NOT is the same thing as a bitwise XOR. if ( S1() ^ 1 ) is the same as if ( !S1() ). Note the above code snippet. Press S1 LED1 turns on and stays on. Press S2 and LED1 turns off and stays off. (This could also be a motor control for example.) In each ca...
wires. Bus levels are divided into dominant and recessive levels, which must be one of them. The sender sends the message to the receiver by making a change at the bus level. When the logical line "and" is executed on the bus, the dominant level is "0" and the recessive level is "...
In your conditions, you can use these test operators: == (equal to), < (less than), > (greater than), <= (less than or equal to), >= (greater than or equal to), != (not equal to). And you can also use the logical && (and) and || (or) operators. ...
