Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

The project illustrates the driving of analog meters using PWM outputs from Arduino as well as the LCD Smartie program. A small current is typically required by meters to operate wherein a typical ...

As high-speed analog-to-digital converters (ADCs) have increased in sampling rate, so has the problem of code errors — also known as sparkle codes — in the ADC ...

If you're into robotics or electronics, you've likely come across Arduino—a small microcontroller that can control sensors and motors for nifty DIY projects. Like the Raspberry Pi, the Arduino is ...

Digital displays are useful for quick and accurate readout, but lots of people prefer the physical motion of a needle moving along a dial. For instance, many smartwatch users choose an analog face to ...
