I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

#define MOTOR_PIN_ENA 9 // Pin for motor speed control (ENA) #define MOTOR_PIN_IN1 10 // Pin for motor direction control (IN1) #define MOTOR_PIN_IN2 11 // Pin for motor direction control (IN2) ...

This project controls the speed and direction of a DC motor using an Arduino, a potentiometer, and two push buttons. It requires an L293D motor driver IC to function. Functionality ⚙ This program ...

Whether you’re using a soldering iron or a table saw, ventilation in the shop is important. Which is why [Atomic Dairy] built a monster air cleaner called the Fanboy that looks like it should be ...
