Mini Washing machine

Washing machine

:: this week we are required to create an electronic device controlled by an ON/OFF switch and make at least two actions at the same time through Tinkercad software and in a real breadboard.

I had a lot of ideas to do but I had the desire to actually make something that we use every day and I experimented with what if I made a washing machine myself

Things don't make themselves, You need some tools and smart software to be able to create your device

Software

From now on, the Tinkercad will become your new friend.

Tinkercad is used for creating digital designs that are ready to be 3D printed or to simulate electric circuits and/or code them. we will use it to simulate an electric circuit before making it in real to test wiring and avoid components burning.

Electronics tools

Resistors

to reduce current flow, and divide voltages

LED

OUTPUT: to track that the device is running

DC motor

OUTPUT: to move the washing machine part

ON/OFF switch

INPUT: to play and close the device

Jumper wires

jumper wires have 3 types male-male wires, male-female wires, and female-female wires. All of these connect two points to each other and make the circuit closed

crocodile wires

to attach components with wires in the circuit

adaptor 5V

to provide a power source for my electronic device

Mini breadboard

is used for building circuits, and demonstrating its action

crafting tools

we need some material to aid us in enclosure such as: -cardboard -glue gun -cutter -scissors - plastic cups

Desiging in Tinkercad

you will be exposed to this program interface of Tinkercad when you decide to create a simulation circuit

the breadboard has 3 sized types, you can choose any type of them but in this project I chose a mini breadboard becouse i didn't have much component

after you choose the circuit button, you get free space for designing and wiring. let's get to know the buttons that make it easier to use the program:

first you will find and search for any components here
if you need to back-step or clear all steps, choose these arrows
you can color wires and make a color coding through the tap of coloring
finally after finishing the circuit wiring, start the simulation to make sure that the wiring is right or has an error

from the components, I chose these components that my circuit is based on:

1- mini breadboard 2- resistor 3- LED 4- slide switch 5- DC motor

6- Power supply

here is the final wiring, I used color coding, red for positive and black for negative. I used an LED and DC motor as output are connected parallel with power, and the input is a slide switch, and sure connect a resistor to avoid LED burning

<< I would like to refer that the parallel connection is the best way to connect for two reasons, due to preserving the appliances Since all devices do not depend on each other for connectivity while the other reason is all the appliances connected to get the same voltage.>>

start the simulation, when sliding a switch to the left the LED lights up and the motor rotates at the same time simulation washing machine when you close the switch, the power doesn't reach to output component, so they are stopped.

<< You may be wondering why we used 5 volts instead of 9 volts!! the data sheet is your guide so we found that the DC motor works from 3V to 12 V but Red LED can work from 1.5 V to 5 V max Therefore if we use 9V, the motor could work without LED.>>

Build a real circuit

before wiring all components together, I checked the health of the LED and motor by testing each component separately

as it showed, I connected components with the breadboard through jumper wires and crocodile wires like the wiring in Tinkercad

Enclosure

to enclose the circuits to be a functional device, you'll need

6 square sides of cardboard (any size you want)
1 plastic cup
1 plastic cap
glue or tab

First, you have to integrate your components so measure the size of the component and open an area for LED, DC motor, switch, and hole for the adaptor, then attach the moving part of the DC motor with a cup, and finally use a tab to stick breadboard and all of the wiring inside the cardboard.

FINALLLLLLLLY, you have a Mini washing machine

Overcoming Challenges

I struggled with the wiring because it was complex and obstructed the movement of the motor in the washing machine, through trial and error I reached the best solution to facilitate the movement :

I changed the type of plastic, and used a plastic cup instead of a plastic bottle, so the movement became smoothly before the wiring
I stuck every wire together to reduce the space occupied by wires, so the area of movement increased

>>> For a perfect experience, I encourage you to increase the size of the cardboard to move it more smoothly >>>
