Learn electronics, coding, and projects — step by step.
Control structures are programming constructs that allow you to control the flow of your Arduino sketch. They help your program make decisions, perform repeated tasks, and respond dynamically to inputs such as sensors or buttons. Without control structures, an Arduino program would simply execute commands sequentially from top to bottom, making it impossible to handle real-world interactions effectively.
Variables are used to store data in your Arduino programs. They hold values that can be numbers, characters, or true/false states, and can be used throughout your sketch.
The Blink sketch is the classic first program for Arduino. It helps you test that your board and IDE are working correctly by making the onboard LED blink.
Understanding the physical layout and pins of an Arduino board is essential for connecting sensors, actuators, and other components correctly.
he Arduino IDE (Integrated Development Environment) is the software used to write, verify, and upload code to Arduino boards. It also allows you to monitor and communicate with the board through the Serial Monitor.
