8th Grade Bimestral Test

When programming and Arduino we use this block of code to set the inputs and outputs.

• public void()

• void setup()

• void loop()

• void conditional()

What is the difference between analog pins and digital pins in Arduino

• There is no difference.

• Analog pins can only output binary values.

• Digital pins can only output binary values while analog pins can read varying voltages.

• Analog pins can only output binary values while digital pins can read varying voltages.

This is the code for a basic counter in Arduino. Describe the purpose of line 23: Serial.println(i);

• This line initializes the variable i

• This line prints in the communication port the variable i

• This line defines the condition i

• This line defines the inputs and outputs in the system.

To solve this error in the code we need to

• declare the variable i at the end of the code.

• declare the variable i in line 20 of the code.

• erase the line highlighted.

• declare the variable i at the begining of the code.

Spot the error in this circuit

• the push button is upside down

• the resistor is disconnected.

• the push button is not conected to the positive line

• the green wire should go to ground.
