Raspberry Pi running Raspian (Linux based) C#;. PWM in Raspberry Pi PWM is a technique of controlling the output voltage by varying the Duty Cycle of a stable DC voltage signal at fixed or varying frequency thereby allowing you to obtain an average output voltage level anywhere between the minimum and maximum signal level The two main PWM parameters are Period and Duty cycle. Pulse Width Modulation (or PWM) is a technique for controlling power We use it here to control the amount of power going to the motor and hence how fast it spins The diagram below shows the signal from the PWM pin of the Raspberry Pi.

Finally attach the positive terminal of your fan to the 5v pin of your pi or external power supply About Temperature driven PWM fan controller for raspberry pi over GPIO, designed with retropie in mind. At 50°C the Fan goes up. A small script to turn your fan on and off via GPIO and PWM Through this together real quick last night, it's crude but does the job HAPPY PI DAY!.

If your fan doesn’t support PWM control, then you can see #138 Variable Speed Cooling Fan for Raspberry Pi using PWM and PID controller or PWM Regulated Fan Based on CPU Temperature for Raspberry Pi to use a BJT transistor to use PWM control The fan’s RPM signal is an OC(OpenCollector) circuit design (in most fan), so you’ll need a pullup resistor to measure output waveform according to Noctua PWM white paper. Also there are no native PWM on Raspberry Pi PWM are quite useful to control components with a nonbinary command You can fake the PWM from software (ex with WiringPi), but it’s clearly not recommended as it will take a lot of CPU and won’t be really fast I won’t make the complete list here, but you see the point.

Software The Raspberry Pi was originally created to teach kids software development, so Raspbian comes with full Python support In addition, there is a great python library called RPiGPIO which allows your python program to interact with the onboard pins There are many ways to get the code onto the RPi. Regarding the fan’s PWM needs, Noctura has an application note that describes the required signals – 25kHz (2128kHz) at, loosely, TTL levels A note on fans here as far as I can find out, threepin fans tend to have power in and a tachometer output, to which fourpin fans add a PWM control input. However, the GPIO pins on the pi can only deliver 33V with a maximum of 16mA each we cannot — and should not — feed the motor with the pin’s power Huston, we have a problem (?) What we need is some sort of relay that can be activated by a standard pin to draw current at full throttle to our fan.

An Adafruit IO dashboard has a slider control for deciding the fan speed between 0% and 100% Upon a value change message via MQTT, the Raspberry Pi then adjust the output of the PWM signal to match the message from Adafruit IO The Circuit The fan used in this project is one typically found on desktop PCs It operates at 12V, needing a driver. PWM Pulse Width Modulation Fans are useful devices that create airflow to cool something down, provide a fresh supply of air, or help the circulation of aerosols Most domestic fans have different speed settings, but these are often in the form of mechanical buttons, which may be difficult to control using a Raspberry Pi.
