Tell us about your assignment's idea for this week. Why do you care about this idea? What inspired you? (Please include images or links to sources of inspiration)
This week's assignment is to design, simulate, and build a simple electronic device that performs two actions. After searching a lot, I chose to build a drawing bot as a simple toy for my little siblings. I thought it would be fun for them to watch something like that and teach them something about automation 😆. The idea basically is based on the vibrations of motor movement with wooden clamp and it draws random lines and circles on paper with its color pen legs.

Circuit connection on tinker cad
Circuit design:
On Tinkercad, I started to put the components I will use in my circuit.
The circuit consists of two action components (OUTPUT) which are the dc motor and the light bulb connected in parallel.
Also a switch is connected in series as an ON/OFF action.
I used a 5v adaptor to power the cirucuit.

Circuit Implementation and mounting:
I determined the dimensions of the cardboard based on the length of the color pens.
I cut the parts of the body and smaller ones for head.
After that, I started to connect the circuit on the mini breadboard:
I connected the 5v adaptor with the socket and connected it to the breadboard
I then put one of the motor terminals and one of the light bulb terminals on the same line
Then I put the other terminal for both also on the same line to connect them in parallel
I connected the switch in series with both of them.
I used crocodile wires for the light bulb and the switch along with jumper wires
In order to minimize space I tied the wires.
After I made sure the circuit is working, I mounted all the components in the cardboard after I assembled it together.
I made holes for the motor, switch, light bulb on head and the power source.
Finally I connected the wooden clamp with the motor and turned it on to see the masterpiece.
Panels are cut with desired dimensions
Glued together and holes are made for components
Light bulb place on the head
Wires are tied to minimize space
Circuit exactly like tinkercad
Switch is mounted on the side
Dc motor is mounted on back
5v adapter power socket
Light bulb place bottom view
All wires are compacted and enclosed
Glued the googly eyes
Final look front side

As I have only 5 crocodile wires, this wasn't enough to connect the switch (2 wires) and the light bulb (2 wires) and the dc motor (2 wires). So, I decided to use the knowledge I gained from the extra session about soldering and borrowed the required tools from a friend and I connected two old wires of mine with the motor and it worked fine!

How can you use the skills and knowledge that you've acquired this week in your final project?
I got the sense of enclosure, how to place components and how to power them. In addition, I got some experience in make electronic circuits.
WOW!

The WOW moment happened when we controlled the motor movement with circuits only using the H-bridge circuit. It was really an amazing moment.
