We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function the ...

You can adjust the spinning speed with a potentiometer and you can also set a minimum and maximum speed in the code. You will need an Arduino board, a potentiometer (I have used a 50K one), as many ...

Circuit Diagram. Circuit diagram for Arduino DC Motor Speed Control using PWM is geven below: Code and Explanation. The complete code for Arduino DC Motor Control using potentiometer is given at the ...

Sometimes, a hack isn’t really about the technology but about the logistics. If we asked you to light up an LED using an Arduino, there’s a good chance you’d know exactly how to d… ...
