In battery-powered applications in which power management is key, a microprocessor may adjust its core voltage corresponding to an increase or a decrease in clock speed, allowing full processing power when necessary but not wasting excess power when idle...

Boost converters, like other switchers, have traditionally received their control signals from a dedicated circuit. However, a recent trend is to integrate simple switching-power-supply building blocks into generic devices, such as microcontrollers...

By decoding the commands sent by a direct-broadcast satellite receiver that uses the DISEqC protocol, you can troubleshoot the commands or simply listen in...

This design idea shows how easily “new flesh can be added to the old bones” and how some new functions can be added to the simple LED display that was published earlier...

Here are some simple tips for servo systems that may improve productivity and prevent costly downtime...

This handheld electric PCB drill speed controller is cheap, easy to build, and only uses a few components. Basically, it is an Arduino Uno based PWM controller that operates at a relatively high frequency...

This expandable LED display for a microcontroller has a simple interface with only 6 data/control wires and can be easily accommodated to a DIY design. The display has static indication...

If you need to quickly and inexpensively convert a binary number into a proportional analog voltage, one cool way to do it is...

Despite the increasing availability and declining cost of on-chip analog peripherals, the humble PWM DAC retains its appeal as a “free” DAC that can repurpose an uncommitted DIO pin and counter/timer module...

Many applications, such as medical therapies, magnetic stirrers, and induction heating, call for a rotating magnetic field, which you can generate by attaching multiple permanent magnets to a dc motor...
