Use the pulse width modulation signal(PWM) generated by the Playstation 3 for it's internal fan in conjuntction with an Arduino Mega to control an external fan that circulates air inside the enclosed ...

A small script that allows Arduino to separately set the speed of two standard CPU fans. In order to control those fans the Arduino needs to generate a PWM signal at 25 kHz frequency. This is ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

In this arduino based project, we are going to build a temperature-controlled fan using Arduino. With this circuit, we will be able to adjust the fan speed in our home or office according to the room ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using the ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...
