Assignment Idea:
My assignment idea for this week is about the electric bell.
I chose it because it’s simple, useful, and something most people are familiar with in daily life. I care about this idea since the electric bell is a common device that shows how electricity can be converted into sound and movement. It’s also practical.
We use bells in homes, schools, and many other places.
What inspired me is the fact that such a small device can make communication easier, like alerting someone at the door or signaling in classrooms. I like how it connects science with real-life applications.

Design and Preparation Process:
Design and Preparation Process:
Voltage Source (5V):
For my project, I used a 5V power supply.
I chose 5V because it is safe for small electronic components such as the LED, buzzer, and switch.
A higher voltage (like 9V) might damage the LED or make the buzzer too loud, so 5V was the best choice for stability and safety.
Type of Circuit (Parallel):
I designed the circuit in a parallel connection.
This means that the LED and the buzzer are connected in separate branches to the power source.
The reason for choosing parallel is that if one component (for example, the LED) stops working, the other (the buzzer) will still work. This makes the circuit more reliable.
Simulation in Tinkercad:
Before building the real circuit, I tested it on Tinkercad.
I placed the power supply, LED, resistor, switch, and buzzer on the virtual breadboard.
The simulation allowed me to see how the circuit worked when the switch was pressed (the LED lights up and the buzzer makes sound).
Design and Preparation Process:
Sketched the model of the electric bell on paper.
Measured and cut cardboard with a cutter, pencil, and ruler.
Glued the parts together to make the body of the bell.
Using Tinkercad (Software):
Designed the circuit virtually with breadboard, jumper wires, buzzer, LED, resistor, and switch.
I made the circuit in parallel.
Tested the connections in Tinkercad to check if the circuit worked correctly.
Corrected mistakes in the virtual design before building the real model.
Implementation:
Built the circuit on the breadboard using jumper wires, crocodile clips, and power supply.
Connected the buzzer and LED to show how the bell works.
Attached the circuit to the cardboard model to complete the project.

Implementation Process (Breadboard & Electric Circuit)
Implementation Process (Breadboard & Electric Circuit)
Power Supply Connection:
I started with a small breadboard.
From the power supply (through the rozeta), I connected two wires:
Red wire (positive) → to the first row of the breadboard.
Black wire (negative) → to the first row of the breadboard.
2. Buzzer Connection:
I placed the buzzer near the LED on the breadboard.
The positive leg of the buzzer was connected below the positive rail.
The negative leg of the buzzer was connected below the negative rail.
This way, the buzzer shared the same power source as the LED.
Testing the Circuit:
I examined the setup by connecting the power supply.
Both the LED lit up and the buzzer produced sound, proving the circuit worked.
Adding the Switch:
To control the circuit, I added a switch:
I removed the red jumper wire (positive) from the first row.
I connected one terminal of the switch using a crocodile clip to the positive source wire.
I replaced the removed red jumper with a brown jumper wire to act as the new positive line.
The brown jumper was then connected to the other leg of the switch using another crocodile clip.
This way, the switch controlled the flow of electricity to the LED and buzzer.
Final Check:
After reconnecting everything, I pressed the switch.
The LED turned on and the buzzer rang only when the switch was pressed, showing that the electric bell system was successfully implemented.

Planning with Tinkercad (Software Stage):
I first used Tinkercad to design the circuit virtually.
I connected the power supply (5V), switch, LED, resistor, jumper wires, and buzzer on the breadboard.
This allowed me to test the circuit and make sure everything worked before I built the real model.
Tinkercad helped me avoid mistakes and understand how electricity flows in the electric bell.
Preparing the Cardboard Model (Fabrication Stage):
I used cardboard, white paper, ruler, pencil, cutter, and glue to make a small house-shaped model for the bell.
The cardboard dimensions were:
Base (main board): 12 cm × 8 cm
Back wall (vertical support): 12 cm × 15 cm
Side walls (x2): 15 cm × 5 cm each
Roof (optional): 14 cm × 6 cm
Front doorbell box (button & LED): 6 cm × 4 cm × 3 cm
✂️ Cutting Instructions:
Cut one rectangle 12 × 8 cm → base.
Cut one rectangle 12 × 15 cm → back wall (attach vertically to base).
Cut two rectangles 15 × 5 cm → side walls.
Cut one rectangle 14 × 6 cm → roof (a little wider to cover).
Cut one small box 6 × 4 × 3 cm → to mount button & LED.
Electronics Placement (Assembly Stage):
I used 4 crocodiles for fixed and move the led , buzzer
i used 2 famle_ famle jumper wire to move the LED .
The push button was fixed on the small box front.
The LED was placed just above the button.
The buzzer was placed behind the LED inside the small box.
The power supply (5V) stayed outside to connect easily.
Final Model:
The electronic circuit from Tinkercad was transferred to the real model.
The cardboard structure made it look like a small doorbell system.
When the switch was pressed, the LED turned on and the buzzer produced sound, showing how an electric bell works.

I asked my instructor Yassin for feedback on my idea, and he agreed that making an electric bell was a good choice.
While I was designing the circuit on Tinkercad, I faced a problem: the components were not working properly with the switch. I asked Yassin about this issue, and with his guidance, I discovered that two wires of the switch were connected in the wrong place. I corrected the mistake by putting them in the right position, and then the circuit worked.
This experience showed me the importance of checking connections carefully.
Yassin’s suggestion helped me improve my circuit and complete the assignment successfully.
I also tried to help my peers by sharing how I fixed the switch connection, so they could avoid making the same mistake. In return, my peers encouraged me and gave me ideas on how to present my project more clearly.

One of the challenges I faced during my assignment was that I only had 5 crocodile clips, but my circuit needed 6 to connect all the components. At first, this stopped me from completing the connections.
To solve this, I carefully traced the circuit visually and thought about alternative ways to connect the parts. After some trial and error, I found a solution: I replaced the missing crocodile with a combination of female-female, male-female, and male- male jumper wires. This allowed me to complete the connection to the LED and continue testing the circuit.
The key to solving this problem was creative troubleshooting and trying different wire combinations until I found one that worked. I didn’t use an online tutorial for this specific issue, but I relied on my understanding of how breadboard and jumper wires work.
This challenge taught me that even with limited materials, I can still build a working circuit by being flexible and using the resources I already have.

I really was enjoyed in this theme I really like it ,😍
This week, I learned how to design and test circuits on Tinkercad, how to connect components correctly on a breadboard, and how to fix wiring mistakes like with the switch. I also improved my skills in using craft materials (cardboard, ruler, cutter, glue) to make a model that looks neat and clear.
I can use these skills in my final project by:
Designing the circuit on Tinkercad first to avoid mistakes.
Building and testing the circuit step by step on a breadboard.
Using materials like cardboard to create a professional-looking model.
Applying what I learned about switches, LEDs, buzzers, and resistors to make more complex circuits.These skills will help me make my final project more accurate, creative, and easier to present.🥰
