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)

assignment revolve about build a simple electronic device that performs two actions.

Doorbell with Light Fixed on the door

A doorbell with an integrated light fixed on the door.

The idea is simple, as I want to create a straightforward device that serves a practical purpose. The inspiration came while I was scrolling through Facebook and came across a photo that sparked the concept. Upon reflection, I realized that I already had the necessary components in my kit to bring this idea to life. عشان كدا اعتمدت الفكرة

The combination of an auditory signal (the doorbell) that the presence of a visitor is noticed. and visual cues (Light) to help visitors see in the dark.

Tool Chain

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

Software

Google Photos, Pinterest, and Facebook: used for research, gathering design ideas

Tinkercad: For simulation.

Machine:

Multimeter: To test the connections and verify the circuit's functionality.

materials

Design: Pencil, paper, eraser
Measurement and Planning: Ruler
Cutting the Cardboard: Craft knife, cutting mat, scissors
Assembly and Joining: Hot glue gun, glue sticks, masking tape
Cardboard: As a primary prototyping material, cardboard was selected for its versatility, ease of use, and cost-effectiveness. It allowed for rapid iteration and testing of different design ideas.
Electric components: Buzzer, push-bottom with a redhead, 2 push-bottom with two legs, 2 white LEDs, Jack for DC adaptor, 5 Volt DC Adaptor, Switch bottom, 2 Resistors 220 Ohm, small breadboard and wires.

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?

Design and Preparation Process:

1. Conceptualization:

Idea Generation: I began by sketching out the basic idea on paper, visualizing how the doorbell and light would be integrated into a single, simple circuit. I considered the layout and placement of components, such as the push button, LED, resistors, and power source in Tinkercad.
Component Selection: Based on the simplicity goal, I chose components that I already had in my kit, ensuring they were basic but functional.

2. Circuit Design Using Tinkercad:

Tinkercad Simulation: I used Tinkercad to create a digital prototype of the circuit.
Designing the Circuit:

the first switch that is close to the power supply is working as an on/off switch
led in a series with the on/off switch
buzzer and ring bottom ( push bottom ) are series with each other
LED and the buzzer are parallel with each other

- Power Supply Configuration: I simulated using a 5V battery to power the circuit.
- Testing and Troubleshooting: In Tinkercad, I ran simulations to check if the buzzer rings when the button is pressed. This helped identify and correct any wiring or component placement errors before moving to physical assembly.

3. Preparing for Fabrication:

Gathering Materials: I gathered all the required materials, including the Buzzer, push-bottom with a redhead, 2 push-bottom with two legs, 2 white LEDs, Jack for DC adaptor, 5 Volt DC Adaptor, Switch bottom, 2 Resistors 220 Ohm, small breadboard and wires.
Tool Setup: I set up the multimeter to be ready for use in the final assembly and testing phase.

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?

1. Circuit Assembly on Breadboard:

Component Placement:
- I began by placing the components (push button, LED, resistors, buzzer) on the breadboard according to the layout planned during the design phase.
- put the plug of the DC adaptor in the back for the view.
- The Switch Bottom was placed in a central location, with two terminals connected to the power supply. which works as an On/Off switch.
- The LED was positioned at the top of the Door.
- The buzzer was positioned beside the two LEDs
- And the Ring bottom in the middle of the front view on the right.
Wiring the Connections:
- Using jumper wires, I connected the components based on the schematic diagram.

2. Testing the Circuit:

Initial Power-On Test:
- After assembling the circuit on the breadboard, I connected the 5V battery to power the circuit.
- I pressed the push button which works as an ON/OFF switch to check if the LED lights up as expected, then pressed the doorbell bottom to check the buzzer indicating the circuit was working correctly.

3. Final Integration and Mounting:

Mounting the Components:
- Once the circuit was verified to work correctly, I considered how it would be mounted on the door.
- The LED was fixed in a position that would be easily visible from outside the door, and the push button was placed at a convenient height for use.
- The circuit had to be enclosed in a small housing.
Final Test:
- After the circuit was mounted and enclosed, I performed a final test to ensure everything worked as expected.
- This test involved pressing the button to see if the Buzzer rings and verifying that the entire setup is securely mounted and functional.

Final Shot

Overcoming Challenges

What kinds of challenges or problems did you face while doing the assignment, tutorials, or exercises? How did you solve them? Did you ask for help from an instructor or peer? Please provide a link to the tutorial or article that you used to solve your problem (if any)

In Tinkercad, I encountered an issue where I needed to press two push buttons simultaneously but wasn’t sure how to achieve that. Thanks to Menna, I learned that holding down the Shift key while clicking on each push button allows you to select and interact with both simultaneously. This tip was crucial in accurately simulating the behavior of multiple push buttons in the circuit design.

2. Troubleshooting Circuit Connections:

Problem: During the testing phase, the circuit did not work as expected. The LED didn’t light up even when the push button was pressed. This issue was likely due to a loose connection or an incorrect wiring setup.
Solution: I used a multimeter to check the continuity of the circuit and identified a loose wire connection on the breadboard. Re-securing the wire in the correct slot fixed the problem. I also ensured all other connections were solid and matched the schematic.
