Cheryl’s IoT and Final Project Planning

Final Project Ideation

A trashcan makes a buzz sound and light up when it detects BuBu come close and try to dig through the trash.

Final Project List of Materials

  1. Arduino Board
  2. Ultrasonic Sensor:
  3. Buzzer 5V:
  4. LED x 1-3
  5. Resistor
  6. Breadboard
  7. Jumpwires
  8. Translucent Acrylic sheet 12×12 (3 pieces): OR
  9. Two way mirror acrylic sheet 12×12 (3 pieces):

I havent figure out the code yet but this is what I am planning to do.

Monica’s IoT #2 and Bill of Materials for Final Project

IoT Homework

My Huzzah is connecting to the internet now! I also successfully got the Adafruit IO feed working when I pressed the switch in the LED circuit.

and then the IFTTT part also worked and I got an email!

Still gotta figure out the copy, lol.

Tilt switch

Succeeded, though not without some trouble obviously.

Oops, spammed myself. Clearly working though.

PIR sensor

Note: learned in class that it’s not really a distance sensor but an infrared sensor. So gotta test it again inside a box.

Final Project: Mood tracker


Niha and I will be working on this project together. We want to create a mood tracker for all the POD students to record how they are feeling at the beginning of each day. Our board will have an LED strip light embedded in it that lights up each time you walk past it with the PIR motion sensor to prompt you to record your response. The board will have a thumbs up, thumbs middle or thumbs down that students can press to record how they are feeling with the feedback of a lite button.

Circuit diagram

We will make the circuit on later on
