Sarah’s Final Project Progress


I started testing my circuit on Tinkercad. I’m using a Feather Huzzah board to connect to 2 sets of LEDs and a Hall Effect Sensor (HES). Because the HES turns the LED’s on/off I’m unsure whether the HES output is the LED input. I know the LED needs to receive code info from the Arduino so I made two circuits. One where the HES output in the LED input and the other where they are both connected to different pin #s. I’m confused if either is correct.

I linked the IFTTT Fitbit applet to Adafruit IO. The applet should trigger at a certain time and send Adafruit IO information on my daily steps but so far it has not worked. It was saying that the ‘there is an issue with the trigger’ I reconnected my Fitbit app to IFTTT it no longer says there is an issue but it has not fired and there has been no update on the IO.


I assume I will have to set multiple of these applets for the different times of day I want to be updated on my steps instead of it automatically updating.

I am using the Fitbit App on my phone as my step calculator. Could that be the issue?

Circuit Prototype

Questions for Becky:

  • How do we wire the Ultrasonic distance sensor? (Don’t see 5V nor the data pin)
  • Where is the 5V pin in the Huzzah?
  • Couldn’t find the normal NeoPixel strip in, only found this weird one. Do you know where to download the normal NeoPixel strip Fritzing library?
  • Couldn’t find a simple LED strip on Do you know were these might be?
  • Why is the code not connecting to WiFi? It doesn’t even show up on the Serial Monitor
  • Can we cut a metallic breadboard into smaller parts? Or are the smaller metallic breadboards?

Coding Progress

I set out to get the Huzzah+pushbutton+LED+NeoPixel circuit from Lesson 5, but couldn’t make it work, so I had to rewind all the way back to the simple Huzzah+pushbutton+LED sketch. After a long time I figured out the issue and got the simple sketch to work on a fresh breadboard. I also successfully had it connect to WiFi and got it to send data to Adafruit IO.

However, when moving on to the sketch with the NeoPixel, the LED turns on fine but it doesn’t connect to WiFi anymore. This shows on the Serial Monitor.

Arshi’s final project – WIP

Global Time Tracker

My family and friends live all over the world. From Mauritius, to the UK, and Australia. That’s a lot of countries with a lot of different time zones. Sometimes I’ll try to call or message my friends back in Australia and wonder why they never pick up. The time difference does not make it easy. The world globe light will help me with just a click to know what time it is in another country so I can plan when to call or message them

Use Case Scenario:

Calling my family and friends is very important to me because I live so far away from them. I have to set up so many different time zones on my clock app on my phone just so I can track what time it is in their country.

Final Project concept

For my final project, I want to do a timezone lamp because it’s always hard for me to track what time it is when I need to call my parents or my family who all live in different parts of the world.

The first idea is a globe light. When you touch any part of the world, it lights up and tells you the time in that chosen country.

The second idea is a refrigerator grocery reminder. When I first stock on grocery items, I can input the items by pressing a button which will light up. When a produce is running low, I will immediately know that I need to restock.

The third idea is a timer to better manage my time with my assignments. It’s an orange sliced into 5 pieces. Each slice indicates a 10 mins timer. When all 5 slices timer is up, the orange will light up. To start my 10 mins break, I can remove one of the slice and start it as an individual slice. After my break, I can repeat the cycle.

Final Project Concepts

1. Thinking of you

This product comes in a pair, you keep one and gift a loved one the other. When you want to let the person know you’re thinking about them, you can place your palm onto the shape and the other person’s shape will light up. When both yours and their hand are on the shape, both will light up in a different color.

2. long ceiling lamp

Unlike most ceiling lamps which are globe-shaped and hang very high up, I want to create a sculptural light design that is quite flat and at eye level, which you can change the dimness by tapping the center or when you come closer, it dims.

3. FINAL – cube light

Each of the three panels has its own circuit so you can tap change the color on each individual panel by tapping them, allowing for fun, experimental, and truly customizable light experience.

Carter’s Works in Progress/Proposal/Arduino Attempt

I tried at school, on my hotspot and at home and could not connect to the internet.

I’d like to either do a matrix display welcoming someone when front door is open or a dress (or skirt) that is motion activated for my niece. If it’s a dress, maybe the top is sound activated (since it’s not moving) and is red lights (school color) and the motion part is white lights of the skirt. I would consult with Monica and Nihaarika about tips from their Halloween costume.

Xinyue’s IoT #2 and Final Project Ideation

IoT Exercise

The whole process went smoothly. My Huzzah can connect to the internet. I also successfully got the Adafruit IO feed working when I pressed the switch in the LED circuit.

Final Project Ideation

The applause device for social software and the mini music stage are both interesting, but I am more enthusiastic about the mini music stage and can’t wait to have my own stage. Every music practitioner desires a stage, but not everyone has a stage, and not everyone likes to participate in that kind of public stage. I hope I can create a brand new experience for music learners. When you play a piece of music, the lights on the stage will light up rhythmically. This is one of the motivations for you to learn music, and it will make your playing more fascinating.

I have been looking for a music-related Applet on the IFTT platform for a long time, but there is no function to recognize the input of notes. Hence, I went to the website to inquire about music-related product cases and found the following 2 cases.


1. What I am a bit confused is that to achieve the effect I want to achieve now, do I still need the control of the Internet of Things?

2. It seems that the music box in a video can only be connected to audio, and then the light changes rhythmically.
Is it through the component named “audio connect” here?

3.In another case, it can visualize the music by recognizing the external music, but if we play with a single instrument, will there still be such an effect? And, in this case, what components did this effect achieve?

4.I want to implement the first case of changing the brightness of the light according to the music played outside, and I can also change the color of the light by myself. What kind of components should be used?

About stage design materials

I will consider using diffuse with multiple materials and try my best to create a dreamy stage. For example: acrylic, feather, yarn, 3d printing.

I also need to make a new round of sketch design for its stage design and choose the one that works best.

My final project is going to be desk pedometer. This product will be used instead of relying on your iPhone or Apple watch to remind you to get up from your desk and start walking. It is a decorative desk piece that will light up to show you your progress towards walking 5,000 steps.

Infinity Experience – Concept Evolution

Infinity Window – Reference Images

So after some ideation, I’m moving away from a bowl structure that you put your head in, to a “window” into the cosmos that is mounted to the wall. This increases the accessibility of the installation so people of different heights will have different views of the star field.

I’m considering including sonified data from NASA to bring this piece to life. It would be really cool if the star field reacted the sounds, lighting up and dimming.
