Assignment:
This week's assignment is to design, simulate, and build a simple electronic device that performs two actions and is Integrated within an enclosure.
I chose to make a House alarm
Software: We used Tinkercad to simulate the circuit before we use the real electronic components.
Material:
Cardboard
Exacto knife& Ruler
Tap
Pencil&Paper
Electronics components
Resistor (220 Ω)
Red LED Light
Pushbutton
Piezo Buzzer
DC Power (5v)
Breadboard
Arduino UNO Board
jumper wires (per need)
TINKERCAD Simulation
I used TINKERCAD to simulate the circuit before I started to Build your circuit on a breadboard and test it.
First: I used ( LED light, Resistor, Piezo buzzer, Pushbutton, 5v power supply)
Then: I started wiring them:
The LED light's Cathode side is connected with a 220 Ω resistor, and the Anode side is connected to one side of the pushbutton.
The buzzer's negative side is connected to the power supply's negative side, and the positive side is connected to the same side of the pushbutton the LED is connected.
One side of the pushbutton is connected to the LED and the buzzer, and the other side is connected to the power supply's positive side.
Finally: I connected them all to the 5v power supply.
Real Circuit Prototype
I started to collect the component I need from my electronic kit.
Note: in this picture, I used the 5v adaptor on the first try, then I used 9v adaptor on the second try as it maskes the sound of the buzzer and the led's light more clear (I will mention that below)
I didn't know how to wire the circuit in parallel, so I googled it and found this and I understand how to wire it.
I wired the LED light the same way in the TINKEDCAD simulation.
(The resistor is connected to the cathode side and the blue jumper is connected to the resistor, the red jumper is connected to one side of the pushbutton)
I wired the buzzer the same way in the TINKEDCAD simulation.
(the yellow jumper is connected to the positive side of the buzzer and is connected to the same side of the pushbutton the LED is connected, the purple jumper is connected to the negative side of hte buzzer and is connected to the power supply's negative)
all -real prototype- wiring process video.

For the enclosure:
I used cardboard for the enclosure, I cut out all the main parts, then, on the front side, I cut out a circle and cover it with a piece of a transparent plastic bag, also I cut out the pushbutton place. and assembled them with the tap, finally, I taped the circuit inside the enclosure.
real prototype video
On the first try, I wired the circuit in series, also I wired it in the wrong way; so that it didn't work in the real prototype.
So I tried to figure out where is the wrong, so I tested the component separatly, and tested the jumper wires with AVO.
All is good!.
then, I started to build it again and finally, I discovered where is the wrong,
I haven't connected the negative side of the buzzer.
On the second try, after I finished wiring the circuit in parallel, it didn't work while I start the simulation, and that was because I wired the second side of the pushbutton to the negative side of the power supply, it was supposed to connect to the positive.
electronics make me confused, every time I hade debuge in the curciut, thanks to my team they explaned the wiring to me and checked if I wired it correctly, and corrected it for me.
This assignment aims to understand the basic circuit analysis, how to connect components optimally to prevent them from overheating or burning out, and how to assemble and organize components in an enclosure without shortening the circuiting or messing up the circuit. also, -Knotting the jumper wires- tip on the breadboard to make them shorter, in order to keep the circuit clean and easier to debug for problems
My final project contains RGB LED light, Buzzer, and a pushbutton, I learnt how to connect them in parallel.
Making the sumo RC cars, I really enjoyed all the process and the fight
IN the EOWeenk session we are asked to make a SUMO RC Car that is controlled through pushbuttons and operated via H-bridge circuits, and is Integrated within a laser-cut enclosure,
Tools & Materials that we used
Design & Fabrication
Autodesk Fusion 360
RDWorks
Laser Cutter
Electronics
2 Yellow DC Motors
8 Push Buttons
Jumper Wires
2 Adapters (9 V)
2 Large-sized Breadboard
2 Rounded Wheels
1 Caster Wheel
2 Zip Ties
Yellow Tape
Ahmed Hammad, Abdelrahman sidiki and I were in a team, we started with building the circuit in the breadboard and tested it, then we moved to the design part to design our car, finally, we cut it with the laser cutter and assembled the parts and the curcuit,
building the circuit
testing the circuit
cutting the enclosuer
assembling the car
after all teams have finished the whole process, we started a Sumo Car tournament, every team has two-person to control the car
my team has won .. yaaay!
