![]() The single equal sign is the assignment operator, and sets x to 10 (puts the value 10 into the variable x). So how can we use this? Say we want to make an if statement that is only executed when two variables are less than five. The Arduino programming language Reference. Only when both x and y are true, does the outcome of AND become true. And if both x and y are false, the outcome is false. Similarly, if x is false and y is true, the outcome is false. If x is true and y is false, the outcome of the AND operator is false. This truth table shows how the AND operator works: PC Arduino: Sends data (command) from PC to Arduino. Arrays of characters, which are the same as the strings used in C. For example, the characters that a user types on a keypad connected to the Arduino. Strings are also useful for storing the user input. ![]() This is usually used for debugging and monitoring. They can be used to display text on an LCD or in the Arduino IDE Serial Monitor window. A B checks to see if A and B have the same value. A B takes the value from B and puts it into A. A B or A B system October 13, 2006, 7:04pm 2. The third is that 'do something' is not valid syntax. The second is that is an assignment operator. On the other hand, S is a character, and can be compared to Payload 0. It is used for two purposes: Arduino PC: Receives data from Arduino and display data on screen. As a beginner, I am starting to wonder about the use off Equal values. The first is that 'S' is a string, of length one. The easiest way to visualize logical operations is with a truth table. Serial Monitor is one of the tools in Arduino IDE. The AND logical operator evaluates two variables and returns a true value only when both variables are true.
