Wk 11 HW & BoM for final

I finished Lesson 4 and the first half of Lesson 5 in class, so I don’t have photos or video of that.

I’ve decided to continue working on my bluetooth headphones for the final project. Proposed BoM for the headphones:

  • Microcontroller options:
  • 2 mini addressable RGB LED
  • Lithium battery 150 mAh, 3.7V and charger
  • Translucent ABS plastic (?) composite to 3D print the cover piece for the headphones
  • Plastic housing/neckpiece for the microcontroller (Not sure if I should purchase or try to 3D print it)
  • Cheap flat back BLE earbuds to attach LED and cover piece to
  • silicone covered stranded core wire – 30 AWG
  • White heat shrink tubing
  • soldering supplies
  • Glue to attach LEDs to earbuds. I think something like E6000 would work.

I was hoping to make the headphones wireless overall, like the Bluetooth headphones that hang around your neck. The microcontroller would be on the back of your neck like a necklace.

Week 11 homework

Hello,

Here are my Arduino exercises.

Lesson 5 – CIRCUIT DISPLAYS INTERNET DATA

Whenever I create a data for the weather ‘cloudy’, ‘clear’, or ‘rain’, the neopixel lights up in different ways.

Lesson 6 – COMBINING INPUTS AND OUTPUTS

This was tricky but we figured out that we needed to use the same Adafruit IO id and key.

When my friend hits a button on her circuit, the LED lights up on my circuits.

 

For my final project, here’s the bill of material.

  1. hobby DC gearbox motor or servo motor? (move the light bulb up and down) https://www.youtube.com/watch?v=kUHmYKWwuWs
  2. Power Relay FeatherWing (turn on and off the light)
  3. Stacking Headers for Feather – 12-pin and 16-pin female headers https://www.adafruit.com/product/2830
  4. wires
  5. breadboard or microcontroller
  6. resistor
  7. transistor
  8. lightbulb and socket

 

 

Lesson 4/5/6 and BOM for the final project

For my final project, I decided to make two interactive products that can be used as a communication tool for two people. Below are the things that I am planning to buy. I am planning to make two flower bouquets!

Lipo battery and USB cable X2

Mini vibrating motor X2

vibrating sensor X2

NPN transistor(PN2222) X2

Diode(14N001) X2

100-1K ohm resistor X2

LED sequins or Neopixels

fake flowers

two vases to put flowers in/or fabrics to cover the bottom part

I finished my lesson6 first and then went over to finish lesson 5, but while I was working on lesson 5, my Huzzah started to not work. (sometimes it turns on, but sometimes it does not) So I am posting the photos I managed to finish. I will finish it after solving the problem!

 

 

 

 

More Internet of Things

This week, we continued our exploration in Internet of Things.

First, we connected an LED to Adafruit IO.  In the video below you’ll see that the app on the screen receives inputs when I press the button

In the next section of the assignment, the app sends me an email each time I press the button that also turns on the LED

We also added a neopixel into the mix by incorporating the Adafruit Neopixel library!

I also played around with a widget on my phone.  It was a little hard to take a video, but here is a snapshot of my phone screen

This next part was fun as well as we saw two circuits react identically to an input

Since I am still a little behind on the project, I will need just a little extra time to submit the BOM and circuit.  Will update shortly!

Homework

Hello! Here is my homework for this week:

Lesson 4

Lesson 5

Lesson 6

For the final project ideas, thank you so much Becky for your feedbacks!! They are really helpful!! I have thought about some steps to make it and I am sorry that I have some further questions about the first and the second ideas:

For the first idea, I would love to choose the addressable strip for the material of the light, and for the else part of the product, I am wondering if I could use some 3D printing because it is really hard for hand-making.

For the second idea, personally I like it very much and this week homework helps me a lot about how to make it. For the physical part, I want to use different kinds of felts and learn about the patterns to sew them. If the first idea is hard to actualize I will choose this one to continue with.

Thank you so much 🙂
