Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a ...

Programmable logic controllers (PLCs) are an essential part of the automation sector, particularly factory automation. PLCs are classified as voltage and current inputs and convert real-world signals ...

It is important to consider the use of artificial intelligence (AI) for analog test and measurement, as well as other ...

Let’s face it: analog-to-digital converters (ADCs) operate differently. Their analog inputs are voltage-input-sensitive devices that leave radio-frequency (RF) engineers scratching their heads about ...

Acromag has released the QMC730, a multifunction I/O module in the VITA 93 QMC small form factor (26×78.25mm) that combines analog input, analog output, digital I/O, and counter/timer functions on a ...

The standard analog input for a PC monitor is the Video Graphics Array connection. As technology has developed, many PC monitors have been manufactured accommodate multiple input standards. While VGA ...

In the previous two issues of this newsletter, we looked at troubleshooting digital input modules. Basically, we looked for the presence or absence of a voltage. With analog modules, it's trickier ...

Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...

Q: You had convinced me to wait for the new RX-A3060 until I discovered that it does not have 7.1 analog inputs for my Oppo BDP-105. Though I can connect its L/R ...

Input devices that can handle rough and tumble environments aren’t nearly as varied as their more fragile siblings. [Alastair Aitchison] has devised a brilliant way of detecting inputs from plumbing ...
