Spin Art Machine
Spin Art Machine
For this week's assignment, the idea is to create a low-fidelity prototype of a simple device. I decided to focus on something that could enhance my final project, the Montessori busy board for kids. I was inspired by the spin art machine, which is a fun and interactive way to create art. The idea is to implement a similar mechanism into the busy board, where kids can experiment with colors and patterns, stimulating their creativity and fine motor skills.

TinkerCAD
TinkerCAD
We used Tinker CAD which is a free web app for electronics, coding and 3D design. On Tinker CAD we can create simulations of circuits in which we there is a dashboard that contains all the components needed to create any circuit, we can just drag and drop the component that we want to use, so we can design and test our ideas virtually, which helps us to experiment the circuit before physically doing it. https://www.tinkercad.com/
Electric Components for the circuit:
Electric Components for the circuit:
5 Volts Adaptor
5 Volts Adaptor
5Volts adaptor used as a power supply that adapts electricity of house wall voltage ( 220 volts AC) to low-voltage DC suitable for powering electronics
Mini-Breadboard
Mini-Breadboard
A breadboard is a plastic board with tiny holes. These holes make it easily to insert electronic components to prototype, create electric circuits.
Terminal Block Adapter
Terminal Block Adapter
The terminals are labeled positive and negative, where the positive terminal connected to the center pin of the adaptor.
LED RGB
LED RGB
RGB stands for Red, Green, and Blue, the primary colors of light. An RGB LED, therefore, is a light-emitting diode that combines these three colors to produce over 16 million hues of light.
DC Mini Fan
DC Mini Fan
Mini-Fan with built-in Dc Motor inside it, it can be rotate just in one direction
AVO Meter
AVO Meter
It has 2 usage to troubleshot the circuit like measuring the voltage of power source or a cross a component and also to check the continuity which means to check that the wires are conductive and working good.
Resistors
Resistors
A resistor is a two-terminal electrical component that provides electrical resistance, used to lower the flow of current, divide voltages
Jumper Wires
Jumper Wires
Jumper wires are used to connect components together and it has different types like Male-Male, Male-Female, and Female-Female.
On/Off Switch
On/Off Switch
On/Off switch used to open or close an electrical circuit in a stable manner.
Stationary Materials:
Stationary Materials:
Cardboard
Scissors
Tape
Coloring markers
Double face Tape

Simulating the circuit virtually on TinkerCAD:
Simulating the circuit virtually on TinkerCAD:
Open TinkerCAD and create a circuit.
Drag and drop the needed components.
Assemble the components on the breadboard in which the RGB Led is connected in parallel to the DC Fan, and there are 2-resistors connected in series with the and blue terminals of the RGB, in order to generate purple color.
Add the switch to the circuit so that it can cut the circuit to be controlled from the ON/Off button.
Set the power supply to 5 Volts, set the resistance to 220 ohms.

Building the circuit Physically:
Building the circuit Physically:
Connect 2-wires to the +ve/-ve terminal block adaptor, and connect them to the breadboard.
Assemble the Fan, Switch and RGB Led to the cardboard.
Connect one of the +ve terminal of the fan with the +ve column in the breadboard, and the -ve terminal of the fan to the -ve column in the breadboard.
Connect the 3-terminals of the red, GND, and blue of the RGB with crocodile wires, and the other terminals of the crocodile wire connect them with jumper wires.
Connect the GND terminal of the RGB with the -ve column of the power supply on the breadboard
Connect 2-resistors with the red and blue terminals of the on the breadboard, then connect the other terminals of the resistors to the +ve of the power supply in the breadboard.
Now check that the circuit is working without the switch.
Connect 2-crocodile wires to the terminals of the switch.
Connect the -ve terminal of the power supply to one of the crocodile wires of the switch.
Connect the other terminal of the switch with a jumper wire and put it in the same column of GND of the RGB and the Fan.
Turn on the switch the RGB will light up in purple and the fan will successfully rotate
Spin Art MachineA video present how the spin art machine work.

I wanted to put a potentiometer to control the speed of the fan, it worked on the normal DC Motor on TinkerCAD, But it didn't work in real circuit, i asked the instructor and he told me that the DC Fan will not work with the potentiometer as i wanted to make.

It was a great choice that could be implemented in my final project idea, but after trying it, I felt like it would be better in a separate box, specifically for colouring. 🎨 I suppose it also will not be suitable for the targeted age group of my final project.
WOW!

EOWeek Session
As a robotics coach who has participated in many LEGO category competitions, one of my dreams is to be able to coach teams in the non-LEGO categories. So, I was excited to create a Sumo car competition. 🚗 In the future, I hope that I will be able to coach teams in a Sumo competition with Arduino. 🤖
