Interesting for us enthusiasts is the application of PWM in voltage regulation. Unfortunately the digital pins have a max output of 40mA, and this isn’t enough to power most motors. Want to control fan speed based on CPU or GPU temperature. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 2000 to 1700rpm. There are several methods in which we control the speed of the fan like on/off control, linear control, low frequency PWM and high frequency PWM. It has 16-bit PWM resolution (2 16 ), that is counters and variables can be as large as 65535. I am somewhat of a newbie currently trying to interface the Flir Vue Pro drone thermal camera for a project and was wondering if someone had managed to trigger image capture by connecting the PWM to a Raspberry Pi or an Arduino. When a fan is configured as a 4-wire fan the controller will hold the output of the voltage converter at 12V and control the speed of the fan by generating a PWM signal. It uses the input from two precise DHT22 based temperature sensors. If you like to reduce your system cost you can make a PWM charge controller.
