1. Understanding and Using Arithmetic Operators and Expressions in Arduino Programming A Guide for Beginners Prepared by: [Your Name]

2. Introduction • Arduino programming involves mathematical operations. • Arithmetic operators allow us to perform calculations on variables and values. • Expressions combine numbers, variables, and operators to produce results.

3. Arithmetic Operators in Arduino Definition: Symbols used to perform basic mathematical calculations. + → Addition - → Subtraction * → Multiplication / → Division % → Modulus (remainder after division)

4. Examples of Arithmetic Operators int a = 10, b = 3; int sum = a + b; // 13 int diff = a - b; // 7 int prod = a * b; // 30 int quot = a / b; // 3 int rem = a % b; // 1

5. Arithmetic Expressions • Expression: A combination of variables, constants, and operators. Example: int result = (5 + 3) * 2; // Output: 16

6. Order of Operations (PEMDAS) • Parentheses → () • Exponents → (pow() function) • Multiplication / Division → *, /, % • Addition / Subtraction → +, -

7. Applying Order of Operations Example 1: int x = 5 + 3 * 2; // 5 + 6 = 11 Example 2: int y = (5 + 3) * 2; // 8 * 2 = 16

8. Real-World Application in Arduino • Sensor Calculations → Converting analog input values. • Motor Speed → Adjusting PWM signals. • Timing → Calculating intervals with modulus (%).

9. Summary • Arithmetic operators: +, -, *, /, % • Expressions combine operators, values, and variables. • Order of operations (PEMDAS) ensures correct results. • Essential in Arduino projects for calculations and control.
