Control the speed of your PWM fan easily. No need for other circuits.
This is a model circuit that can control the speed and the direction of a dc motor without the h-bridge ( it's an alternative to h-bridge ).
Making a big digital wall clock using Arduino Mega 2560, 5054 LED strip, DS3231 RTC, IRFZ44N MOSFET transistor, and aluminum profile.
solid plastic servo operated robot gripper.
How to drive an universal AC motor (washing machine) with Arduino and the MST_K07_CL.
Did your somewhat expensive ($50) soldering iron just die? Well then fix it with another one!
Arduino varies speed of DC Motor using PWM and measures its RPM using optical sensor and displays them on LCD
SOFTPWM : DMA+GPIO, not interrupt based, individually controlled, did you ran out of PWM pins?
I will show you how control a motor's speed with one transistor and a personal PWM signal.
Changing the BSP to stop that pesky fan running at full speed.
Using an Arduino MKR and L298N H-bridge to drive a NEMA 17 stepper.
Set up high speed PWM (1Hz - 1MHhz) to one of your IO pins.
Timer one is used in this code and using this the Arduino crystal clock is divided into various small parts microseconds are used for freq.
Follow me as I try to explain how DMA+PWM does the trick with hardware magic in a bluepill. (meme warning)

RAPID PROTOTYPING AND LINUX KERNEL DEVELOPMENT WITH POCKETBEAGLE®
Color of the R G B LED is controlled by an XY Joystick (two potentiometers and button) Position evaluated every 250ms using a timer
This iteration progressed from the CAD design to a first physical build. A lot was learnt along the way.
Iteration 3 of my continuing robot arm project gets a more powerful geared shoulder servo.
