Tell us about your assignment's idea for this week. Why do you care about this idea? What Inspired you? (Please Include Images or links to the source inspiration)

Bermuda

So… I’m ADHD, right? Trying to focus for 25 minutes straight is basically a joke . I needed something that yells at me (literally) when it’s time to work or to finish Maker Diploma Assignments. That’s how Bermuda was born: simple, loud, and slightly annoying, Basically, it yells at me every 25 Minutes so I stop scrolling TikTok. mm perfect for me

Design/Preparation Process

Explain the design and/or preparation process of your assignment. How did you use the tool or software to design and/or prepare your assignment before fabrication/implementation?

I started by designing and simulating the circuit in Tinkercad, placing the Arduino, LED, buzzer, button, and wires on the breadboard.
Tested the connections in Tinkercad to make sure pressing the button would start a 25-second timer, light the LED, and activate the buzzer at the end.
This helped me avoid mistakes before touching the real components.
Once the virtual circuit worked correctly, I moved to the physical breadboard for real testing.

Development/Implementation Process

1- Connecting Arduino to Breadboard

Connect the 5V pin from Arduino to the positive rail on the breadboard.
Connect GND pin from Arduino to the negative rail on the breadboard

2-Connecting the Buzzer

Positive pin of buzzer goes to pin 10 on Arduino.
Negative pin goes directly to GND

3- Connecting the Potentiometer

Left pin to GND
Right pin to +5V
Middle pin to Analog pin A0 on Arduino (this reads the value to adjust time in code)

4- Connecting the LED

Long leg (anode) of LED goes to pin 9 on Arduino.
Short leg (cathode) connects to a 220Ω resistor, then to the negative rail (GND)

5- Connecting the Button

One leg of the button goes to pin 2 on Arduino.
The other leg goes to the positive rail (+5V).

6-Connecting the Buzzer

Mounting the Arduino and components on cardboard

7- Writing the Arduino Code

8-Testing the components before mounting it

Community of Learning

Did you ask for feedback? What are the ideas that others have contributed or suggested? What was someone else’s idea that you built upon? How did you help your peers? How did your peers help you?

I didn’t know if the LED was working or burnt, but a friend showed me a clever trick: using a 3V coin battery to test it easily without powering the Arduino.

Overcoming Challenges

When you got stuck, what/who did you turn to? At what point did you have to pause to research or learn more before moving on? What are some mistakes, pitfalls, or challenges that others can avoid if they were doing this assignment?

1- Verified wiring multiple times to prevent mistakes on the breadboard.

2-The buzzer sometimes stayed on. I did a search on INPUT_PULLUP Concept online, found example codes, and finally understood how to use it properly in my project

I got help from this Website

Title of Media

Final Project

How can you use the skills and knowledge that you've acquired this week in your final project?

I can use the Fusion 360 skills I learned this week like making parametric patterns, using loft and fillet for smooth shapes, and adjusting dimensions accurately. I also learned how to fix scaling issues and prepare STL files properly for 3D printing, which will help me avoid the mistakes I made in my first glasses design.

WOW!

What is the coolest thing that you've learned this week? What is something that you will never forget from this week?
