Characteristics of a Buzzer

• Input, Digital

• Input, Analog

• Output, Digital

• Output, Analog

It's the component that emits sound. You can specify only frequency, or frequency and duration of the tone.

• Push Button

• LED

• Piezo Buzzer

• 7 Segment Display

The result of the following condition when n=20 and m=30

if (n==35) {

Serial.println ("okey");

} else if (m ==20) {

Serial.println("dokey");

} else {

Serial.println("artichokey");

• artichokey

• okey

• dokey

• okey dokey

Which of the following switches is connected correctly?

• 
• 
• 

This is the code we need to create random numbers

• void setup () {

  randomSeed(digitalRead(0));

  }

  void loop () {

  random(7);

  }

• void setup () {

  random(7);

  }

  void loop () {

  randomSeed(3,7);

  }

• void setup () {

  randomSeed(analogRead(0));

  }

  void loop () {

  random(7);

  }

• void setup () {

  random(3);

  }

  void loop () {

  randomSeed(analogRead(3));

  }

This function would give results of 0, 1, 2

• random (analog);

• random (1,2)

• random(0==2);

• random (3);

On a 7 segment display, these are the segments required on HIGH to display 3

• A, B, C, D, E

• B, C, D, E, G

• DP, A, B, C, F

• A, B, C, D, G

Characteristics of a 7 Segment Display

• Input, Digital

• Input, Analog

• Output, Digital

• Output, Analog

You are going to simulate a virtual coin flip that will display a red light if heads and a blue light if tails, at the action of a button.

What elements do you need?

• LEDs, slide switch

• LEDs, push button

• LEDs, potentiometer

• Buzzer, push button

Which of the following conditions would be used to express that a student can apply to a scholarship if their final average is 90 and have 120 hours of social service?

• if (prom >=90 && sshours >=120) {

  Serial.println ("Scholarship");

  } else {

  Serial.println ("No scholarship");

  }

• if (prom ==90 && sshours ==120) {

  Serial.println ("Scholarship");

  } else {

  Serial.println ("No scholarship");

  }

• if (prom >90 | | sshours >=120) {

  Serial.println ("Scholarship");

  } else {

  Serial.println ("No scholarship");

  }

• if (prom >=90 | | sshours >120) {

  Serial.println ("Scholarship");

  } else {

  Serial.println ("No scholarship");

  }
