UNIT - 4Programming the ArduinoQ1) Write a short note on Arduino.A1)Arduino programs are written in the Arduino Integrated Development Environment (IDE). Arduino IDE is a special software running on your system that allows you to write sketches (synonym for program in Arduino language) for different Arduino boards. The Arduino programming language is based on a very simple hardware programming language called processing, which is similar to the C language. After the sketch is written in the Arduino IDE, it should be uploaded on the Arduino board for execution. Q2) Write a short note on Arduino IDE.A2)Arduino IDE The Arduino board is connected to a computer via USB, where it connects with the Arduino development environment (IDE). The user writes the Arduino code in the IDE, then uploads it to the microcontroller which executes the code, interacting with inputs and outputs such as sensors, motors, and lights. Both beginners and experts have access to a wealth of free resources and materials to support them. Users can look up information on how to set up their board or even how to code on Arduino. The open source behind Arduino has made it particularly friendly to new and experienced users Q3) Which computer language is used on Arduino Codes?A3)Arduino code is written in C++ with an addition of special methods and functions, which we’ll mention later on. C++ is a human-readable programming language. When you create a ‘sketch’ (the name given to Arduino code files), it is processed and compiled to machine language.The Arduino Integrated Development Environment (IDE) is the main text editing program used for Arduino programming. It is where you’ll be typing up your code before uploading it to the board you want to program. Arduino code is referred to as sketches Q4) How to import new Library in Arduino?A4)Libraries In Arduino, much like other leading programming platforms, there are built-in libraries that provide basic functionality. In addition, it’s possible to import other libraries and expand the Arduino board capabilities and features. These libraries are roughly divided into libraries that interact with a specific component or those that implement new functions. To import a new library, you need to go to Sketch > Import Library In addition, at the top of your .ino file, you need to use ‘#include’ to include external libraries. You can also create custom libraries to use in isolated sketches. Q5) What is Library structure in Arduino?A5)Library Structure A library is a folder comprised of files with C++ (.cpp) code files and C++ (.h) header files. The .h file describes the structure of the library and declares all its variables and functions. 2. The .cpp file holds the function implementation. Q6) What are variables in Arduino?A6)VariablesWhenever using Arduino, you need to declare global variables and instances to be used later on. In a nutshell, a variable allows you to name and store a value to be used in the future. For example, you would store data acquired from a sensor in order to use it later. To declare a variable, you simply define its type, name and initial value. It’s worth mentioning that declaring global variables isn’t an absolute necessity. However, it’s advisable that you declare your variables to make it easy to utilize your values further down the line. Q7) What Setup() in Arduino?A7)Setup() Every Arduino sketch must have a setup function. This function defines the initial state of the Arduino upon boot and runs only once. Here we’ll define the following: Pin functionality using the pinMode functionInitial state of pins Initialize classes Initialize variables Code logic Loop() The loop function is also a must for every Arduino sketch and executes once setup() is complete. It is the main function and as its name hints, it runs in a loop over and over again. The loop describes the main logic of your circuit.
