Inspirational picture of the design
The assignment of this week was to create a simple useful electronic device that performs two different actions.
I decided to create a very useful device which is a mini handheld night reading lamp with fan by upcycling some leftover cardboard & some old household stuff to apply what I've learned throughout this week about electronics & upcycle old household items to something useful.

I-Circuit (Tinkercad)
Step (1): I started creating the circuit by place LED lamp with power source 5V as LED & I connected it parallelly as it provides 5v for each component of the circuit indevidually .
Step (2): Then, I added motor (fan) parallelly with the power supply with 5v & then adding the potentiometer in series to in/decrease the resistance to control the fan speed.
State (OFF): It's the case while power is switched off & no currant is passing.
State (I): it's the case while power is on but potentiometer is off.
State (II): it's the case while power is on & the potentiometer too.

I-Circuit (Building Components)
Building the designed circuit was super easy.
II-Enclosure (Body)
Building the designed circuit was super easy as I just placed the circuit in a cup made of cartoon then created a holes for rosseta, switch, LED & potentiometer, then added a top cardboard box to place the fan & place it on the cover top of the cup.
III-Circuit (Full Circuit)
Time for testing the product.

The problem I faced was that I wanted to create fan speed with two fixed speeds to provide high & low, which needed to have diode which is a two-terminal electronic component that conducts current primarily in one direction, which actually I didn't have on my kit that's why I decided to add a variable resistor (Potentiometer) to change the resistance that would change the volt trough the fan due to V=IR that would change the fan speed depends on user's needs.

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?
Getting familiar with many of the electric components such as the LEDs, Buzzer, DC motor, resistors, potentiometer & voltage regulator. Also learning how to wire components together whilst keeping in mind the voltage drops on various components is a vital skill. Those could be a couple of the most important skills that I've acquired throughout the week which will be super important at the project.

The RC car completed in the hackathon is probably the coolest thing I've done throughout this week...
