Interface Potentiometer and dc motor with Arduino Uno. Develop an Arduino sketch to control speed of DC motor using Potentiometer.

Here i am using online IDE Tinkercad . If you don't know what is tinkercad then refer my blog HERE or else you can use offline IDE also.

Code :-

int c1 = 0;

int c2 = 0;  

void setup()  {

  pinMode(12, OUTPUT);

  pinMode(A0, INPUT); 

}

void loop()

{

  c2= analogRead(A0);

  c1= 1024-c2;        

  digitalWrite(12, HIGH);

  delayMicroseconds(c1);  

  digitalWrite(12, LOW); 

  delayMicroseconds(c2); 

}

Output :-
