Arduino Week 5 Homework

Label the different parts of the code

a

b

c

d

Use Variable

Turn LED ON

Turn LED OFF

Create Variable

Drag and drop the options below to create the following program:

When the light level goes below 700 units, turn on the LED.

int photoresistor = 0;

int led = 10;

void setup() {}

void loop() {

​ (a)  

​ (b)   ​ (c)  

​ (d)   ​ (e)  

}

• photoresistor = analogRead (A0);
• if (photoresistor < 700) {
• digitalWrite(led, HIGH);}
• else {
• digitalWrite(led, LOW);}

Drag and drop the correct symbols to complete the below program.

void loop() { if (Esplora.readButton(1) ​ (a)   PRESSED) { ​ (b)   ; } ​ (c)   (Esplora.readButton(2) == ​ (d)   ) { Esplora.writeRGB(0, 0, 255); } }

• ==
• PRESSED
• if
• Esplora.writeRGB(255, 0, 0)

Identify what the keywords in the code do.

a

b

c

d

If everything is false this will run

This will loop endlessly

This will run if something is true

This only runs once

How many times will the shown for loop execute?

• 0

• 9

• 10

• 11

What is the command needed for an Arduino to receive information from an analogue device such as potentiometer or similar.

Assume no pin is set and end with ();

Use the code block below to create an IF statement that will do the following:

1 - Check to see if the value from a potentiometer is greater than 0 and less then or equal to 150. 2 - Run a program called RED if true.

​ (a)   ​ (b)   ​ (c)   ​ (d)  

RED();

• if
• (potentiometer >0
• &&
• potentiometer <=150)
• if, (potentiometer <0, &&, potentiometer >=150)
• potentiometer >150)
• if, (potentiometer >=0, &,

What will the following code do when buttonPin is HIGH?

cpp

• A) Turn the LED off

• B) Turn the LED on
