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 ...

Proper thermal dissipation is an essential rule for nowadays electronics. The best operating temperature for the electronic components is 25 degrees (standard room temperature). Thermal dissipation in ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...
