### Lesson 1 (165 minutes)

This lesson introduces students to the basics of a circuit and then students research and present on common components of a circuit

#### Outcomes

• Understand common components of a circuit

### Lesson 2 (110 minutes)

Students create a physical circuit that will light up an LED using an Arduino microcontroller, explore a variety of resistors to understand the role that resistors play in the circuit, and calculate current for their circuit.

#### Outcomes

• Define an open circuit, closed circuit, and a short circuit
• Identify the primary components of a circuit
• Use Ohm’s Law to calculate current with given resistor and voltage values
• List the advantages of using a breadboard during circuit design.

#### NGSS Standards

NGSS Standard Student Action
HS-PS3-5. Develop and use a model of two objects interacting through electric or magnetic fields to illustrate the forces between objects and the changes in energy of the objects due to the interaction. Students use Arduinos to build a physical circuit to light up an LED light

#### NGSS Disciplinary Core Ideas

NGSS Disciplinary Core Idea Student Action
ETS.HS.1C.a Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed. Students follow specific steps to use Arduinos to build a physical circuit to light up an LED light.

### Lesson 3 (135 minutes)

Students use Arduinos to create a circuit to light and LED and manipulate the code to set specific blinking patterns.

#### Outcomes

• Understand the role of a computer scientist when it comes to working with computers
• Blink an LED on an Arduino at a given rate.
• Create a specific blinking pattern such as mimicking a heartbeat or representing a message encoded in Morse code.

ETS.HS.1C.a Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others (trade-offs) may be needed. Students follow specific steps to accomplish a series of challenges using Arduinos.

#### Common Core Standards

Students will interpret functions to create code on an Arduino.
