All of Microchip’s baseline PIC microcontrollers have internal 4-MHz oscillators, which are useful for freeing up one or two pins for I/O use and allowing you to build minimal-component-count designs ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

The major building blocks for a white-LED driver are an oscillator, a charge pump, and a regulated current source. National Semiconductor (www.national.com) produces a device that contains all these ...

Wall clocks! Are they very accurate? Well, sometimes they are, and sometimes they lose minutes a day. If you’ve got one that needs calibrating, you might like this device from [Lauri Pirttiaho]. Most ...

When 8- and 16-bit microcontroller companies spot the opportunities that exist in the emerging net-centric computing-device and embedded Internet market, they sometimes act like deer caught in the ...
