Arduino Week 5 Homework

Label the different parts of the code

a

b

c

d

Turn LED ON

Use Variable

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

This only runs once

This will run if something is true

This will loop endlessly

If everything is false this will run

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
