Mec1 Arduino and Interactive

Code within the following will only run once

• void loop()

  {

  }

• void setup()

  {

  }

• digitalWrite(pin, HIGH or LOW);

• pinMode(pin, INPUT or OUTPUT);

An analogue pin is usually connected to which leg of a potentiometer?

The code delay(250); instructs the program to wait how long?

• 250 seconds

• 0.25 seconds

• 250 nanoseconds

• 0.025 seconds

True or false? An LDR is a type of variable resistor.

The phases of the design cycle are

• draw, plan, make and do

• draw, design, decode and demonstrate

• research, design, construct and program

• research, design, construct, program and test

The component shown is

• a light dependent resistor

• a component with no polarity

• a type of sensor

• an RGB LED

Select all components which output information (ie act as sensors) from the list below

• LED

• LDR

• buzzer

• button

• potentiometer

An interactive device

• is not possible to build with an Arduino and electronic components

• involves lights and buzzers

• allows a user to input information

• must have at least 5 sensors and 4 lights

Select all the Arduino components that can act as outputs

• serial monitor

• wires

• LED

• buzzer

• parallel

The first stage of the design cycle is
