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 ...
ThermaPID is a temperature control system implemented on Arduino using a DHT11 sensor, a brushless pc fan (5V 0.4A), and a PID controller. The fan speed is automatically adjusted via PWM to maintain a ...
#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) ...
