LEDs find their way into applications that range from high-end video displays to low-end lighting applications. Designers often need only some of the functions of a dedicated LED driver but can’t ...

As I get more and more used to analog control of power giving way to digital control, I often look for applications where the microprocessor is controlling the entire show. I do this for several ...

SmartFan Cirrus is a user-programmable, microprocessor-based interface for DC fans with built-in speed control based on a pulse width modulation or voltage control input. It regulates fan speed from a ...

auto-cpufreq 3.0.0 is here: The open-source tool automatically optimizes the CPU speed and power consumption of Linux notebooks by adjusting governors, frequencies, and other parameters based on ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...

Simple electric motors turn when you apply power. They have been used this way since their inception. Yet today, a microcontroller may be sitting between the motor and the switch, and motors can be ...
