 ====== 3 Levels of Programming: C++, Libraries, Assembler ======
-Programming AVR microcontrollers can be divided into three levels: C++, libraries, and assembler. Each of these levels offers distinct benefits and is utilized according to the project's specific requirements.
+Programming AVR microcontrollers can be divided into three levels: C++, libraries, and assembler. Each of these levels offers distinct benefits and is utilised according to the project's specific requirements.
   * **C++** is a high-level language that allows programmers to write code in a more abstract and understandable way. Using C++ for AVR enables advanced features such as object-oriented programming, inheritance, and polymorphism. This makes the code more modular and easier to maintain. Compilers like AVR-GCC convert C++ code into machine code that the microcontroller can execute.
   * **Libraries** are sets of predefined functions and procedures that facilitate programming AVR microcontrollers. An example is the AVR Libc library, which provides functions for I/O, memory management, and mathematical operations. Using libraries enables rapid application development without writing code from scratch. Libraries are particularly useful in projects that require frequent use of standard functions.
-  * **Assembler** is a low-level language that allows direct programming of the AVR microcontroller. Writing code in assembler gives full control over the hardware and allows for performance optimization. However, programming in assembler requires a deep understanding of the microcontroller's architecture and is more complex than programming in C++. An assembler is often used in critical applications where every clock cycle counts.
