Operators in your Arduino sketches (programs) consist of comparison blocks, concatenate strings, bitwise operators, string conversion, ‘not’ operator, and compound operators. These operations generally will be used with other instructions in your sketch. It is important to understand what instructions are available and what they are designed to accomplish.
We will be looking at each of these instructions that are available using productivity blocks. A sample sketch will be shown that will use some of these operators. The sketch will get a number between 1 and 100 from the built-in Arduino IDE (integrated development environment) serial monitor. It will print the number on the monitor if it is between 1 and 100, else it will print try again. Let’s get started!
