Centrifuge

A centrifuge is a device that uses centrifugal force to separate various components of a fluid

I was influenced by the DIY bio team at London University, who created lab equipment using 3D printing, laser cutting, Arduino, and electronics to lower research costs.

Its a prototype for my final project

he idea of the centrifuge is a device that uses a rotor to separate particles from a solution.A centrifuge's rotor applies a centrifugal force to each particle in the sample, which causes the particle to sediment at a rate proportional to the centrifugal force supplied to it. I used the potentiometer to control the speed of rotation and when the device turn of the buzzer works

I used Tinkercad to simulate the circuit and write the Arduino code, after which I used the Arduino software to upload the code to the Arduino tool and make it work.

Arduino, breadboard ,motor driver, potentiometer, slide switch,buzzer Dc motor, jumpers , crocodile wires,adaptor 9 v, card board, and glue gone were used to construct the circuit.

void setup()

{

pinMode(A0, INPUT);

Serial.begin(9600);

pinMode(8, OUTPUT);

pinMode(7, OUTPUT);

pinMode(9, OUTPUT);

pinMode(3, OUTPUT);

pinMode(2, INPUT);

}

void loop()

{

if (digitalRead(2)==LOW) {

Serial.println(map(analogRead(A0), 0, 1023, 0, 255));

analogWrite(9, map(analogRead(A0), 0, 1023, 0, 255)) ;

digitalWrite(7, HIGH);

digitalWrite(8, LOW);

} else {

digitalWrite(3,HIGH);

delay(1000);

digitalWrite(3,LOW);

}

}

After finishing the simulation in Tinker-cad, I began physically constructing the circuit before uploading the code to the Arduino programme. I start with each output and input separately to make sure that all components are work and make troubleshooting easier then I applied the whole circuit Potientiometer analog pin A0 , buzzer pin 3, slide switch pin 2, motor driver pins 9,7,8. potientiometer and switch were inputs and the others output. after that I started to write the code and uploaded it on arduino to function the circuit.
