When it comes to Robotics, I am more fit to be a...

• a Circuit Builder

• a Programmer

• Both

Multiple Choice

In an LED which PIN should be connected to the positive side of the current?

• The LONGER pin

• The SHORTER pin

Multiple Choice

What type of pins are labelled A0 to A5?

• Digital

• Analog

Multiple Select

In a buzzer, which PIN should be connected to the POSITIVE side of the current?

• The SHORTER wire

• The LONGER wire

• The wire that is parallel to the + symbol

• The wire that isn't parallel to any symbol

Multiple Choice

What is the use of a resistor?

• Increases current

• Decreases current

Multiple Choice

Which resistor is best suited for the LED?

• 220 ohms

• 1k ohms

• 10k ohms

Multiple Choice

What is most likely happen if the resistor you used for the LED is the 10k ohm resistor?

• The LED will burn out.

• The LED will explode.

• The LED will be dim.

• The LED will not work.

Multiple Choice

Which is the 220 ohm resistor?

Multiple Choice

Which pin of the resistor should be connected to the positive side of the current?

• Any, the resistor is non-polar.

• The LONGER pin

• The SHORTER pin

• The MIDDLE pin

Multiple Choice

Which is NOT a type of buzzer?

• Active

• Passive

• Hybrid

Multiple Choice

What component does this schematic symbol represent?

• Resistor

• LED

Build Break!

FA1 (Part 1/3): Build the circuit using this schematic

cONNECT THE CIRCUIT TO YOUR PC

• uNPLUG THE aRDUINO

• mOVE THE PIN FROM THE 5V TO PIN 13

• Let's program! Open arduino ide in your computer.

Multiple Choice

What does this button do?

• Verify

• Verify and Upload

Multiple Choice

What are the two functions required in an Arduino UNO program?

• void setup and void loop

• 2 void setups

• 2 void loops

• none of the other answers

Multiple Choice

Since we have our LED connected to pin 13, the code for void setup should be pinMode(13, ________);

• INPUT

• OUTPUT

Multiple Choice

Which one turns on pin 13?

• digitalWrite(13, HIGH);

• digitalWrite(13, LOW);

Multiple Choice

Which code adds a one second gap between commands?

• time(1);

• delay(1000);

• gap(100);

FA1 (Part 2/3)Now create a program for your circuit:

Blink the LED with one second interval. Upload the program.

Multiple Choice

When using a buzzer, which code adds a tone?

• tone(pin, frequency, duration);

• noTone(pin);

Multiple Choice

In tone(pin, frequency, duration); which parameter is optional?

• pin

• frequency

• duration

FA1 (Part 3/3)

Now add a buzzer (see schematic) then make it buzz when the LED is OFF.

Take a 5-second video and submit it individually in AnimoSpace.

Questions?

Summary

• The Arduino UNO Microcontroller has Digital and Analog Pins.

• There are different schematic symbols for buzzer, LED and resistor.

• Resistors are non-polar, buzzer and LEDs are polar.

• The LED and Buzzer are output components of Arduino.

• void setup and loop are required in all Arduino UNO programs.

• tone and noTone are used to produce a sound for the buzzer.
