Arduino provides built-in trigonometric functions that are part of the standard C math library (math.h). These functions allow you to perform calculations involving angles, sine waves, or geometric computations. Trigonometric …

In Arduino, Strings are used to handle text data such as words, sentences, or characters. Strings can be manipulated in various ways to create powerful and dynamic applications. This tutorial …

Pulse Width Modulation (PWM) is a technique used to simulate an analog output using digital signals. PWM is widely used in Arduino to control the brightness of LEDs, the speed …

Functions in Arduino allow you to encapsulate code into reusable blocks, making your programs modular, readable, and efficient. In this tutorial, we’ll explore how to create and use functions in …

Inter-Integrated Circuit (I2C) is a two-wire communication protocol used for connecting microcontrollers to peripherals like sensors, displays, and memory devices. I2C is a synchronous, multi-slave, multi-master protocol that is widely …

Variables and constants are fundamental building blocks of Arduino programming. They allow you to store, modify, and access data throughout your program. This tutorial introduces variables and constants, their types, …

Serial Peripheral Interface (SPI) is a communication protocol used to transfer data between microcontrollers and peripheral devices like sensors, SD cards, displays, and more. It is faster than I2C and …

In Arduino, loops are essential for running repetitive tasks. Loops allow you to execute a block of code multiple times based on a condition. This tutorial explores the different types …

The Tone Library in Arduino allows you to generate sound waves on a digital pin, making it easy to create melodies, sound effects, or audible alerts using a piezo buzzer …

Control statements in Arduino are used to control the flow of execution in a program. They allow you to make decisions, repeat actions, and manage program logic based on certain …

Interrupts in Arduino allow you to execute specific pieces of code immediately when a particular event occurs, regardless of what the main program is doing. They are essential for creating …

Operators in Arduino are used to perform operations on variables and values. They are essential for controlling program flow, performing arithmetic, and making comparisons. This tutorial introduces the types of …
