  • Making fan control simple and easy. The new Universal Fan Controller from Phanteks allows you to connect both 3-pin(DC) and 4-pin(PWM) fans to a single device. Regulate them through manual control with the press of a button, or sync them with the motherboard for automatic fan control.
  • May 13, 2016 · PWM stands for ‘Pulse Width Modulation’. PWM is a method used for getting variable voltage out of constant power supply. We will generate PWM signal from Raspberry PI and demonstrate the PWM by varying the Brightness of a LED, connected to Pi. Pulse Width Modulation: We have previously talked about PWM many times in: Pulse width Modulation with ATmega32 , PWM with Arduino Uno, PWM with 555 timer IC and PWM with Arduino Due.

Hi all, I’m pretty excited to be able to bring this project. It ties together and old Raspberry Pi running latest version of Raspbian with HTTPD and a PHP script. The PHP code runs the gpio command in order to trigger pin 4 of the RPi for a second then turns it off. This triggers a simple 5v relay which in-turn shorts out my gate. The obvious difference of what I’m sharing here is the fact ...
