In which function do we indicate the initial instructions and if the components are INPUTS or OUTPUTS?

• Variables section

• void setup() function

• void loop (function)

• Comments

The following piece of code tells me that...

• indicates that the servo is in the digital pin 90

• None is correct

The LDR (Light) Sensor is connected to...

• A digital pin, Analog pin, and 5V

• A digital pin, GND and 5V

• An analog pin,GND and 5V

• None is correct

delay(2000) means...

• wait 2000 seconds

• wait 2 seconds

• wait 2000 years
