This week's assignment made me think carefully of a problem that I wanted to present a creation to solve it. But at the same time, I wanted to do a simple thing because it's my first time to deal with electronics. My objective was to grasp the basics and apply them very well.
Introducing the "Heat buzzer". I decided that I wanted to create a fan that works both way as a fan and as a buzzer (alarm). To solve the heat in the summer and at the same time emit sound.

First, I planned my circuit and tested it on tinkercad:
I decided that I will use 5v adapter as it fits perfectly the needs of both the piezo and the dc fan, which is the main 2 actions of my heat buzzer.
I decided that I will design the circuit in parallel mode.
I connected the anode and the cathode of the power supply to the breadboard.
Then I connected the anode of the fan to the breadboard, and the cathode as well.
I started to implant the piezo buzzer, I added its cathode to the same line of that of the fan's.
Then I needed to connect the fan's anode terminal to the piezo's so I added a connection between them.
I inserted the On/off switch in series to the whole parallel circuit.
Finally, I tested the functionality of it by simulating the circuit as shown in the video.

2-Implementation of the circuit on the breadboard:
I connected the female jumpers to the breadboard following exactly what I did on tinkercad.
I connected the DC Jack to terminal block converter to 2 female jumper wires and I used the screw driver to tighten its screws.
I connected the on/off switch to 2 crocodile jumpers to the breadboard.
3-Designing the enclosure design and mounting the circuit:
I designed the box that encloses the circuit and took the measurements of the breadboard to fit it in the ground.
I started to make gaps for the on/off switch and the adapter plug.
The wires were already long so I didn't need to create an extension.
I designed the upper part and cut a part for the fan.
4-Testing out the heat buzzer
I connected the plug to the electricity.
It was on mode off, until I switched the switch, then it worked perfectly :)

1- The whole week was a big challenge for me, as I am not really familiar with the electronics world.
2- I had a problem simulating the circuit at first, but found out that I have to long press on the on/off switch to actually work and not just click on it.
3- I had a problem with my resistors and the color coding, so my instructor Ahmed told me to test its resistance using the avo meter and I did so.
4- At first I was going to make a whole different project (multiple led and fan device) , but I faced some problems with the resistors as I found out that I don't have a 220 ohm one.

Basically creating a circuit and implementing it to actually work and not have a mental breakdown over it.
