What differentiates a mixed-signal printed circuit board design from a purely analog board or a purely digital system? What differentiates a mixed-signal printed circuit board design from a purely ...

Many microcontrollers have built-in ADCs (analog-to-digital converters), which means you can use a single device to both digitize analog signals and manipulate the results. Once the ADC digitizes a ...

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

Back in the day where the microprocessor was our standard building block, we tended to concentrate on computation and processing of data and not so much on I/O. Simply put there were a lot of things ...

Producing items onto a screen simply by touching the air is a marvelous thing. One way to accomplish this involves four HC-SR04 ultrasonic sensor units that transmit data through an Arduino into a ...
