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 ...

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 ...

All electronic sensors have their limits on working distances and environmental tolerances. Dynamic range defines a sensor's maximum allowable variations in the signal amplitude. ACG (automatic gain ...

A PWM control circuit drives the MOSFET. Without feedback, the PWM duty cycle determines the output voltage, which is twice the input for a 50% duty cycle. Stepping up the voltage by a factor of two ...
