The document discusses various micro:bit accelerometer applications including:
- Reading acceleration values from the 3-axis accelerometer and controlling it.
- Examples like a electronic dice, movement indicator, tilt control game, and earthquake detector.
- Code snippets are provided for building applications like tracking dice rolls on shakes, showing direction arrows based on movement, and controlling a light sprite in a balancing game.
The document discusses functions in C language. It explains that functions can be divided into built-in functions and user-defined functions. Built-in functions are provided by the compiler as a "black box" that can be called, while user-defined functions are created by the user according to needs. User-defined functions have benefits like reusability, modularity and readability. It also talks about function prototypes, definitions, parameters, arguments, scope, and call by value and call by address.
The document discusses loops in programming. It covers for, while, and do/while loops as well as nested loops. It provides examples of calculating sums and finding narcissistic numbers using loops. Continues and breaks are also mentioned as ways to alter a loop's execution flow.
The document discusses various types of operators and expressions in C language, including: arithmetic operators, assignment operators, unary operators, binary operators, comparison operators, logical operators, and conditional statements like if and if/else. It provides examples of using these operators and statements to perform calculations and make comparisons. The key concepts covered are operators, expressions, arithmetic operations, assignment, increment/decrement, comparison, logical operations, and if/else conditional statements.
The document discusses variables and basic data types in C language. It covers topics such as variable and memory, basic data types, variable declaration and usage, truncation and overflow, address operator (&), constants and symbolic constants. The key points are:
1) A variable is a container that stores data in memory and its content may change as the program executes.
2) Basic data types include char, integer, float, etc. Each data type occupies a different size of memory and has a specific range of values.
3) Variables must be declared before use, specifying the data type and name. The variable name is a reference to the memory location where the data is stored.
