A far more useful case is to provide a power supply for the microcontroller programmer, which has no wall wart. Today’s microcontrollers consume less current than their predecessors, so you can easily ...

Anyway, I was assuming that I'd have to go out of the serial port and into a microcontroller of some kind to turn the bitstream into a raw voltage corresponding to percentage of processor usage.

Ok, the title is a bit misleading. Like most things in life, it really isn’t infinite. But I’m going to show you how you can use a very interesting Linux feature to turn one serial port from a ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

So I'm trying to detect through Visual Basic 6.0 when a voltage change occurs on one of the pins of the serial/parallel port. The whole thing is pretty simple; no data transfer/handshaking/etc ...

Many industrial and instrumentationsystems need to measure theduration of pulse inputs, such as frequencyfrom rotational-speed sensors,gating and strobe pulses from externalsystems, and PWM ...
