Ideation

Spin Art Machine

The idea came that I wanted to design a game for adults and children that allows them to draw and develop their creativity skills, so I searched for an idea or a game in Google that could help to draw and create, and I found Spin Art Machine

In YouTube, I found many videos that we can make at the lowest cost and at home The link, other link

Tool Chain

Software:

I used Tinkercad to simulate my electronic circuit

Tinkercad is an online tool for designing and simulating circuits, 3D models, and code. can drag and drop components, connect them, and run simulations to test how they work. It’s useful for those who want to learn electronics and Arduino without physical hardware.

The Material

cardboard

tape

sticky notes

Marker pens

Electric Components for the Circuit:

crocodile wires

Mini-Breadboard

helps organize connections without soldering.

Resistors (330 Ohm)

Limit current to protect the led

Ensure proper brightness and prevent damage.

jumper Wires

Connect components to the breadboard.

Buzzer: Produces sound when powered.

White LED: Emits bright white light when current flows through it.

On/Off Switch: Controls the flow of electricity in a circuit.

DC Mini Fan: Spins using DC power to cool or move air.

5 Volts Adapter:

Supplies a stable 5V power to circuits.

DC Female Power To 2 Pin Screw Terminal Block: Connects a DC power source to wires using a screw terminal.

Design/Preparation Process

Open Tinkercad: Go to Tinkercad Circuits and create a new circuit.
Add Components: Drag and drop the following:

Breadboard
DC Mini Fan
White LED
Buzzer
330Ω Resistor
5V Power Supply
On/Off Switch
Push Buttons
Terminal Block Adapter

Assemble the Circuit:
Connect the LED, DC fan, and buzzer in parallel: Both share the same positive and negative terminals.
Connect the Resistor: Attach one end of the resistor to the negative leg of the LED and the other end to the negative wire.
Add Push Buttons: Integrate push buttons to control power flow, allowing the circuit to be interrupted or activated via the On/Off switch.
Set the Power power supply to 5V.

Run the Simulation: Click "Start Simulation" to test if the circuit functions as expected.

Development/Implementation Process

Start to Build the circuit :

connect the 2 wires of the terminal block, the positive and negative, to the breadboard

connect the on/off switch with crocodile wires and jumper wires to the breadboard

connect the DC fan to the breadboard in the positive and negative pines with jumper wires

connect the LED and resistance in the breadboard

connect the buzzer to the breadboard

the video of the components are turned on

Assemble the components in the cardboard.

Assemble the fan, switch, LED, and buzzer to the cardboard.

connect the wires from the breadboard to the fan, switch, LED, and buzzer

The Video of the Art Spin Machine that I make

Overcoming Challenges:

I had trouble installing the LED on the cardboard and plugging it into a wire to work.

The solution I install the wire with the duct tape in the LED terminals so that it is fixed and not taken off.

Also, I had a problem at the beginning of the electrical circuit. I used the DC motor instead of the DC fan, and the motor worked slowly. I tried to solve the problem by switching volts from 5 to 9 volts, but there was another problem: the light worked with a large current that could lead to its burning if it worked too much, and also when the assembly in the cardboard did not spin well and the LED and buzzer were poor.

I swapped it for DC fun and it was a good choice.
