What are variables in Arduino programming? Variables are containers used to store data in your program — such as numbers, characters, or logical values. They let your code remember and manipulate information while the sketch runs. What types of variables are commonly used? Arduino supports several data types for different kinds of information: int – […]
What is the first sketch to try? The first program most beginners try is the Blink sketch. It demonstrates how to control a digital output pin by turning the onboard LED on and off at regular intervals. How do I load the Blink example? In the Arduino IDE, go to File → Examples → 01.Basics […]
What are the main parts of an Arduino board? An Arduino board typically includes a USB port for uploading code, a power jack for external power supply, and a reset button to restart the program. What are the power pins used for? Power pins provide voltage and ground connections for sensors and modules. Common pins […]
What is the Arduino IDE? The Arduino IDE (Integrated Development Environment) is where you write, compile, and upload code to your Arduino board. How do I install the Arduino IDE? You can download the desktop version or use the Arduino Web Editor online. How do I set up my board? Select the correct board model […]
