Week 8

Date 10/26

• Topic: Digital Fabrication 4 (Arduino Advanced)

Pre-class

• 1. Arduino Research
  • Research the capability of Arduino of what we can do using Arduino.
  • Google with keyword “Arduino projects” “Arduino project ideas”.
  • Or visit Instructables.com and search Arduino projects.
  • Pre-class assignment
    • List top three Arduino projects interested in you. Post on your Open Portfolio on the weekly reflection page.
      • 1) _________________________
      • 2) _________________________
      • 3) _________________________
• 2. Watch 3D Printing video “What is 3D printing?” by Institute for Manufacturing (IfM), University of Cambridge
  • Pre-class assignment. Post on your Open Portfolio on the weekly reflection page.
    • How does the 3D printing technology change manufacturing?
    • What can you do with a 3D printer?

In-class:

• Arduino Anatomy

  • Arduino Sensors
    • Watch the below video and explore Arduino sensors.
    • Advanced Sensor Project (example)
    • For more information, visit Microsoft Hacking STEM
    • Go to the website The List of 21 Arduino Modules.
    • Discuss how we can use sensors in Arduino projects.

• Arduino Outputs

  • Light
    • LEDs
    • LED strips
  • Display
    • LCD
    • 1 Digit – 7 segment display
    • 4 digit – 7 segment display
  • Sound
    • Passive Buzzer :on/off the sound
    • Active Buzzer : can control the sound signals
  • Motions
    • DC Motor: Direct current motor. In Arduino, we can control speed by changing the duty-cycle of each PWM signal.
    • Servo Motor:  a rotary actuator or linear actuator that allows for precise control of angular or linear position
    • Step Motor: fully rotate with micro control of the unit because it divides a full rotation into a number of steps.
  • Others

• How to develop an Arduino project?

  • Develop your design idea first. In most cases, Arduino can perform everything that you want.
  • Think through input-process-output.
    • Identify which sensor can best performs the function of your project.
    • Identify which output can perform your desired goal.
  • Obtain mechanism of the sensor and output. In general, the module designer provides it with its source codes.
  • Tip! Find the similar Arduino project on Google or Instructable.
  • Design circuit using TinkerCAD and test it out. However, some sensors need the physical configuration of the Arduino circuit.

• Project Project 3: Design an Automatic Hand-Sanitizer Dispenser.

  • Grouping
    • G1: Alex, Lowman, Dennis, Saralynn
    • G2: Jhorvi, Mike, Islam, Ronaldo
    • G3: Raul, Richard, Esau, Victor
  • Using above the Ultrasonic sensor and a servo Motor, design a hand-sanitizer dispenser
  • Project details
    • Find a Hand-Sanitizer product from the Internet.
    • Design a physical mechanism that automatically operates the dispenser by the Ultrasonic sensor.
    • Lab report should include
    • a sketch of your hand-sanitizer dispenser. Recommend to use TinkerCAD.
    • a circuit diagram with Arduino and source codes.
    • a short description of its making processes.
    • Anticipated outcomes.
  • Post the project worksheet to your Open Portfolio. In open portfolio, you can share your group design but you should write your own individual reflection and summary.
    • Due Oct 30rd (Friday) 5pm.
• 3D Printing (if time allowed)

• • • Quick 3D design & print on 3D printer.

Post-Class:

• • Assignments
    • 1. Lab report – post your Hand sanitizer project on your Open Portfolio.
    • 2. Reflection – write a short reflection on today’s learning.
    • 3. Prepare for Lab report 4. Arduino Project Research
      • Arduino Project (Next week)
        • Present Arduino projects that you found.
        • Discuss the working mechanism of Arduino on the projects.
        • Explore how you can use Arduino to solve real world problems.
