Questions and Answers
- 1.
Types of microcontroller memory which is slower to access.
- A.
On-chip
- B.
Volatile
- C.
Off- Chip
- D.
Non -Volatile
Correct Answer
C. Off- ChipExplanation
Off-Chip memory refers to the memory that is located outside the microcontroller chip. This type of memory is typically slower to access compared to on-chip memory because it involves communication with external devices, such as RAM or Flash memory. Accessing off-chip memory requires additional time for data transfer and retrieval, which can result in slower overall performance. In contrast, on-chip memory is located within the microcontroller chip itself, allowing for faster access speeds.Rate this question:

•Which of the following code will Sets pin to either INPUT or OUTPUT
- A.
DigitalWrite(pin, value)
- B.
DigitalRead(pin)
- C.
Digitalset(pin, values)
- D.
PinMode(pin, mode)
Correct Answer
D. PinMode(pin, mode)Explanation
The correct answer is pinMode(pin, mode). The pinMode() function is used to set a specific pin on the microcontroller as either an input or an output. The "pin" parameter represents the pin number that we want to configure, and the "mode" parameter determines whether the pin should be set as INPUT or OUTPUT. This function is commonly used in Arduino programming to define the behavior of a pin before reading or writing data to it.Rate this question:

- A.
Sketch
- B.
Digital
- C.
Analog
- D.
Sketch
Correct Answer
B. DigitalExplanation
The given statement is referring to the value of a variable in Arduino, which can be either HIGH or LOW. In Arduino programming, digital variables are used to represent binary states, where HIGH represents a logical 1 or true, and LOW represents a logical 0 or false. This is commonly used for controlling digital pins, where HIGH can turn on a component or activate a circuit, while LOW can turn it off or deactivate it. Analog values, on the other hand, can have a range of values between two extremes, whereas digital values are limited to just two states.Rate this question:

•Which of the following code will set Pauses for a few milliseconds
- A.
DelayMicroseconds(us)
- B.
Sleep (us)
- C.
Delay(ms)
- D.
Sleep(ms)
Correct Answer
C. Delay(ms)Explanation
The correct answer is delay(ms). The delay(ms) function is commonly used in programming to pause the execution of a program for a specified number of milliseconds. This allows for controlling the timing and synchronization of different parts of the program. By using delay(ms), the program will pause for the specified number of milliseconds before continuing with the next line of code.Rate this question:

Which of the following code will Reads HIGH or LOW from a pin
- A.
DigitalWrite(pin, value)
- B.
DigitalRead(pin)
- C.
Digitalset(pin, values)
- D.
PinMode(pin, mode)
Correct Answer
B. DigitalRead(pin)Explanation
The correct answer is digitalRead(pin). This function is used to read the value (HIGH or LOW) from a specified pin. The digitalWrite() function is used to write a value (HIGH or LOW) to a pin. The digitalset() function is not a valid Arduino function. The pinMode() function is used to set the mode (INPUT, OUTPUT, or INPUT_PULLUP) of a pin.Rate this question:

Correct Answer
A. FunctionExplanation
A function is a block of code that has a name and a set of statements that are executed when the function is called. It allows for modular programming and code reusability, as functions can be called multiple times from different parts of the program. The name of the function is used to refer to it and call it whenever needed. When the function is called, the statements inside the function's block of code are executed in order.Rate this question:

•It is the symbol used to end the statement in Arduino programming.
- A.
Braces
- B.
Comment
- C.
Semicolon
- D.
Parenthesis
Correct Answer
C. SemicolonExplanation
In Arduino programming, the semicolon is used to end a statement. It indicates the completion of a line of code and separates multiple statements within a program. By placing a semicolon at the end of a statement, it tells the compiler that the current line of code is finished and it can move on to the next line. Without the semicolon, the compiler would interpret the code as incomplete and generate an error. Therefore, the semicolon is crucial in Arduino programming to ensure proper syntax and execution of the program.Rate this question:

Correct Answer
B. Block commentExplanation
Block comments are areas of text in Arduino programming that are ignored by the program. They are used for adding large text descriptions of code. Block comments are enclosed within /* and */ symbols and can span multiple lines. They are useful for providing explanations, documenting code, or temporarily disabling a section of code without deleting it.Rate this question:

- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The statement "x!= y specifies x is greater than Y" is false. The "!=" operator is used to check if two values are not equal, not to compare their magnitudes. It does not provide any information about whether x is greater or smaller than y.Rate this question:

Microprocessor, by-itself, completely useless it must have external peripherals toInteract with outside world
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because a microprocessor alone cannot perform any meaningful tasks without external peripherals. These peripherals are necessary for the microprocessor to interact with the outside world, such as input devices (keyboard, mouse) and output devices (monitor, printer). The microprocessor processes data and instructions, but it relies on these external peripherals to receive input and display output, making it useless on its own.Rate this question:

Microcontroller put a limited amount of most commonly used resources “inside” the chip
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Microcontrollers are designed to have a limited amount of commonly used resources integrated directly onto the chip itself. This includes components such as a CPU, memory, input/output ports, timers, and sometimes even analog-to-digital converters. By having these resources built-in, microcontrollers are able to perform their intended functions without the need for additional external components. This integration also helps to reduce the size, cost, and complexity of the overall system. Therefore, the statement "Microcontrollers put a limited amount of most commonly used resources 'inside' the chip" is true.Rate this question:
