Emergency Alarm
Emergency Alarm
Salma's Emergency Alarm!!
I was thinking of simple circuits that I can apply easily so after searching on google, I designed an emergency alarm!

I used it to design the electric circuit before I apply it for real and burn the components XD
Machines & Materials
Machines & Materials
Adhesive tape, phone holder, scissors, knife -as cutter-, pen, ruler, & cardboard

I used these materials to design the device. I used the knife instead of cutter and phone holder for shooting the video!

I build the emergency alarm circuit using this kit.

Emergency Alarm Circuit
click on the photo to see the simulation.
The components that appear in the design are:
Power supply (adaptor), mini breadboard, pushbutton, Jumper wires, LED, Buzzer, and resistors.
I connected the +ve terminal of the power supply with the breadboard.
I connected one side of the pushbutton with the +ve terminal of the power supply. And the other side of the pushbutton is connected with +ve terminal of LED.
Then I connected the resistor with -ve terminal of LED and power supply.
I took a jumper wire to connect the +veterminal of the pushbutton with the buzzer. Then I connected the -ve side of the buzzer with the -ve of the power supply.
(parallel cercuit)
I used a 5V power supply because the LED works with 2V while the buzzer needs 5V and by connecting them parallel, each component will receive 5V.
The LED is attached to 220-ohm resistance so it can take the 3V that excess. I chose 220-ohm by applying ohm's law (Voltage= Current*Resistance). The maximum current in the circuit is 20mA. The excess voltage that the resistance will receive is 3V so the optimum resistance is 150-ohm. Thus I chose the resistance with the nearest value which was 220-ohm.
Development/Implementation Process
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?

First Step: Build the Circuit.
I started by building the circuit as I designed in Tinkercad but instead of attaching directly the pushbutton and LED in the breadboard, I used male/female jumper wires to make them more flexible to move around.
I tried the circuit and it worked (not from the first time for sure)
I started to build the body of the device using cardboard. I outlined the shape on the cardboard then I cut it and used the adhesive tape.
Second Step: Build the device.
Third Step: Addition of Circuit to the body.
I inserted the circuit inside the body of the device I made. Then I opened 3 holes on the cardboard. one for the LED, others for the pushbutton and adapter. I made sure that the circuit is working.
I closed the body of the device by cutting a rectangle from the cardboard that is smaller in size than the body so it can be easily added or removed so I can edit my circuit anytime and very easily.
I added a speaker feature which I made from cardboard so it can look more like an emergency alarm and also hide the Arabic words that appear on the cardboard.
It worked! (click on me to see Salma's Emergency Alarm)
Fourth Step: Close the body and add some extra features for the design.

I shared my idea with the instructor and he thought it's a nice idea.
Overcoming Challenges
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?

These beautiful LEDs that appear in the adjacent picture are actually burned by me :)
I know that the outlined circuit on tinkercad worked but I made a mistake in connecting the resistance to the circuit, instead of attaching both terminals of the resistance in two different rows, I put them in the same row.
Also, I connected the pushbutton in a wrong way at the first. When I connected the circuit to the power supply the buzzer starts to make noise immediately without any human intervention. so after looking at the circuit, I realized that I connected the +ve terminal of the power supply with the pushbutton, buzzer, and LED.
It wasn't a technical problem but I faced trouble with taking a video while I test the device so I thought of using the phone holder I made and it worked!

Final Project
Final Project
How can you use the skills and knowledge that you've acquired this week in your final project?
How can you use the skills and knowledge that you've acquired this week in your final project?
Since my final project includes electronic parts so this was very helpful. I actually used the output components that I need for my final project and knew how to connect them to the circuit.
WOW!
WOW!
What is the coolest thing that you've learned this week? What is something that you will never forget from this week?

This week was an interesting and not an easy one for sure. I enjoyed electronics for the first time in my life. I also enjoyed burning the components because they really gave me a hard time trying to connect them! but mostly I loved when the circuit worked and the actions happened in front of my eyes :)
This week was legen -wait for it- dary! legendary!

I build too many circuits this week but the first tutorials were the best for me and here is one of my circuits!
lets light the dark good people :)
