This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an ...

A circuit used to control the level of a video signal should have a 3-dB cutoff frequency of greater than 5 MHz for a television application or 100 MHz for a monitor application. CMOS-based digital ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...

Analog circuits today are typically biased from ±5 V to ±18 V. But the trend is toward lower voltages. For this reason, many components are designed to operate primarily in ±5-V systems. One example ...
