Pwm fan controller arduino

ESCs, in a broader sense, are PWM controllers for electric motors. The ESC generally accepts a nominal 50 Hz PWM servo input signal whose pulse width varies from 1 ms to 2 ms. When supplied with a 1 ms width pulse at 50 Hz, the ESC responds by turning off the motor attached to its output. In this circuit, for controlling the speed of DC motor, we use a 100K ohm potentiometer to change the duty cycle of the PWM signal. 100K ohm potentiometer is connected to the analog input pin A0 of the Arduino UNO and the DC motor is connected to the 12 th pin of the Arduino (which is the PWM pin). The working of Arduino program is very simple ... One of the easiest and inexpensive way to control stepper motors is to interface L298N Motor Driver with Arduino. It can control both speed and spinning direction of of any Bipolar stepper motor like NEMA 17. If you are planning on building your own 3D printer or a CNC machine, you will need to control a bunch of stepper motors.

To verify this, I hooked up the official fan to a pi 3b+ I use for GPIO testing. I plugged the blue wire into GPIO 12 since the standard pin (GPIO 14) doesn't have the hardware PWM you need to exceed 7kHz. Then I used sysfs to enable PWM control and verified that I could fine-tune the fan speed by changing the duty cycle. A couple more notes:
