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 ...

To build a real-time temperature control system using an Arduino board, DHT11 temperature sensor, PWM-controlled cooling fan, and a Peltier module. The system monitors temperature continuously, ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The device is simple to use: just simply connect the PWM capable fans to the board, and power it using a 12 V DC power supply. The device uses an LCD screen to show information. The LCD screen turns ...

So Manual control choices looks like this: 0.75PWM value/Centigrade ~ 2.25 PWM value/Centigrade, with .5 increments in between. This may as well be Greek to me. I get that fan speed should increase ...
