Week #5-Journal

Ideation

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 sources of inspiration)

source of inspiration

I'm working on developing a simple electronic device that can perform two main functions:

Emit light (such as a flashing LED)
Make noise or sound (like a buzzer or speaker)

These functions are essential for my project, as I plan to integrate them into an educational game or use them in my final project, which will include an alarm system. The alarm will serve as a reminder for patients to take their medication, ensuring they don't forget and are prompted at the right time. The light and sound will act as attention-grabbing signals, making the reminder both noticeable and effective.

Tool Chain

Which software/machines/materials did you use in the assignment? Why?

Google: For searching and gathering inspiration
YouTube: For searching and gathering inspiration
Tinkercad: A software to design and simulate electronic circuits
Cardboard: Used to create a simple casing for the device, hold the circuit, and provide a visual and functional space for the components
Electronic components: Such as LEDs , buzzers ,wires ,adaptor 5 v tranisitor and switch

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?

My device is designed to resemble a brain-shaped alarm, symbolizing mental overload, and triggers an alert when it is pressed too much.
The device simultaneously outputs two signals: light and sound. It uses an LED to emit light and a buzzer for sound, both controlled by an on/off switch.
I powered the device using a 5V adapter, with the buzzer and LED connected in parallel through a resistor. The switch, however, is wired in series with the adapter.
I used Tinkercad to simulate the circuit, ensuring that the pressure sensor and alarm system function properly.

Development/Implementation Process

Explain the development/implementation process of your assignment. How did you use the machine/tool to manufacture or implement the design of your assignment?

The electrical circuit is prototyped on a breadboard but at the first i used push button rather than switch on/off

connections

The buzzer and LED are connected in parallel, so they both receive power and activate simultaneously. The switch is connected in series with the power source, controlling the entire circuit. When the switch is on, both the buzzer and LED turn on; when off, they turn off.

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?

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?

Initially, I wasn’t aware of the difference between a switch (on/off) and a push button, so I mistakenly thought the push button was a type of on/off switch and used it in my device. After reviewing the technical requirements, I realized that a push button wasn’t permitted. To correct this, I replaced the push button with a proper on/off switch.
In my first attempt, I mistakenly connected the on/off switch in parallel with the adapter. When I powered the circuit, the LED and buzzer activated, but at a low frequency when the switch was off. After re-wiring the switch in series with the adapter, the connections functioned properly, and everything worked as expected.

Final Project

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

I learned the idea of making alarm

WOW!
