Success Criteria From last meeting

In my work, I am able…

1. To consider others by behaving during class.

2. To identify the requirements for Robotics.

3. To adhere to the rules and regulations for everyone's safety.

Lasallian Virtue of the week

Prudence - the ability to govern and discipline oneself through the use of reason.

"I shall act accordingly in class in order for everyone to enjoy their learning experience, including me".

Inspirational Message of the Week

Joke of the Week

Learning Targets
At the end of the lesson, I can...

1. To recall the components used in Robotics 7.

2. To build a simple circuit that utilizes the LED and Buzzer.

3. To program a simple circuit that utilizes the LED and Buzzer.

4. Apply these technical skills to propose practical solutions for real-world situations

Open Ended

Where do I usually see a single LED in real life?

Poll

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

Open Ended

Why do you need a Piezo Buzzer when you could just have a speaker system?

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.

Extra Challenge

For those seeking for a challenge, replace the sound into a tune that you want. Make sure it is less than 3 seconds long.

Questions?

What are some practical uses for this circuit?

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.
