Lesson Objective

Do Now (2 min) Answer in your notes:

1. So far, we've learned how to Blink and fade lights on and off! Why is it useful to know how to do that? What kinds of technology applications might that be used for?

2. Beyond changing the code to change the pattern of the lights, are we able to physically adjust them in some way to turn them on or off? Or to get them to blink faster or slower? why or why not?

Arduino Unit - Section 2: Sensors

Recap of Section 1 Goals

• Reviewed circuitry basics
• Learned how to use a Breadboard
• Gained familiarity with Arduino IDE
• Programmed an Arduino to turn an actuator (LED) on and off
• Used PWM to simulate voltages between LOW (0V) and HIGH (5V)
• Gained experience using these functions:
• pinMode( ), digitalWrite( ), analogWrite( ), delay( )

Section 2 Goals

• Review Helpful Resources for Arduino Fans
• Learn how to collect measurements (signals) from sensors, including:
• Push Button, Photoresistor (LDR), Force- Sensitive Resistor (FSR), and Potentiometer (Pot)
• Use measurements from a sensor to control an actuator (Simple System)
• Gain experience using these functions:
• digitalRead( ), analogRead( ), Serial.println( )

Sensors!

• Devices that convert other forms of energy (mechanical, light, etc...) into electrical energy.
• Use input pins to detect changes in electrical energy.

Arduino Sensors: Push Button

Assignment

For today

• Open Tinkercad Circuits and show me your Push Button Sketch.
• Then setup the physical version of the Push Button.
• Then return to Circuits and complete Challenge One, Challenge Two, and Challenge Three (in Circuit!).
• Choose your favorite and set up that circuit in the real world to demo for the rest of the class.

Your assignment:

• Part 1 (due today): In Tinkercad Circuits, wire the Push Button circuit, program, and test your code/circuit.
• Part 2 (for our next class): In the real world, wire the Push Button circuit, enter the code in Arduino Create, verify, upload, and test.
• Part 3 (for our next class): Answer the reflection questions on this worksheet, and choose two challenges to complete.

To begin:

1. Pick up your assigned Macbook (work with a partner)

2. Go to Google Classroom and open assignment 02.11 Arduino_Push Button.

3. Follow all instructions, answer all questions, capture all screenshots.

Expectations: Retreiving & Returning Electronics components

Expectations: Retreiving & Returning Electronics components

• Only retreive Arduino and electronics components when given approval by the teacher.
• Use care when retreiving, using, and returning the equipment. Keep and care for the arduino box. You will return the arduino inside of the box.
• Gear MUST be put away at 8 minutes before the end of the period. Failure to do so will result in a reduction in mastery.
• Place everything neatly back exactly where you found it.
