Arduino Uno Programming Codes for Beginners

Arduino Uno is very popular both among beginners and Professional. It is because Arduino Uno programming codes is simpler and easier to learn compared to other microcontrollers. This particular device has simplified C language with the help of Ardunio libraries. Therefore, beginners can learn this language easily. This microcontroller is also popular for other reasons. Some of them are affordable, open source software, and open source hardware.

Arduino Uno Programming Codes for Beginners

Basic Arduino Uno programming codes

As a beginner you must learn the basic Arduino Uno programming codes first before you start your own robotic or electronic projects. It is important to remember that you need to write the Arduino Uno programming codes carefully. It is because this microcontroller language is case sensitive. Therefore, you really need to pay attention at the lower case and upper case while writing the programming language.

When you are writing Arduino codes, you usually need to end it with semicolon. However, you may not need it in certain cases. There are at least two sections that you must fill in writing the code. One of them is ‘void set up’. It is for setting up the serial baud rate, pin modes, and initialize variables. The other one is ‘void loop’. It is the code’s main part and will loop back onto itself.

When you are writing the codes, you must complete them with detailed explanations in the form of comments. Comments are used for textually explaining the codes. The more comments you write, the better it is. It is because a good code usually has a lot of detailed comments. In writing the comments, you must start it with certain punctuations. One-line comments are written differently from multiple-line comments. If you are going to write a single-line comment, you must start it with double slashes (//). You must follow it with textual explanation without a space. If you are going to write a multiple-line comment, you must start it with a slash and a star (/*) and end it with a star and a slash (*/).

Blink LED programming

With Arduino Uno, you can program the blink of the LED. You can find the blink LED code in the software. First you need to open the Arduino software first. After that go to ‘File’ and then click ‘Examples’. After you click examples, go to ‘Basic’ and choose ‘Blink LED’. You will automatically get the code on your window. Once you get it, you can transfer it to the Arduino. However, you must make sure that you pick the right board and COM port. After you connect your Arduino properly, this code will be transferred to this microcontroller. Don’t forget to click the ‘Upload’ button first to see the LED starts to blink.

In order to set the LED blink properly, you must set the program correctly. One of the things you need to consider is the time interval between blinking. You must also consider how many seconds the LED is on. Hopefully, this basic knowledge of Arduino Uno programming codes for beginners can help you more understand about this microcontroller programming.
