It breaks up the 20 V signal into four separate 5 V bands. Of course, one could almost accomplish this by just using an Arduino Due, which has a 12-bit A/D converter (almost, because it has a ...

[Andrew Moser] has a method that lets you pull it off with an Arduino and an LM339 quad comparator. The circuit works by feeding a signal in from the Arduino. This waveform is affected by the LC ...

In this circuit, the infrared emitter IRED1 is modulated by connecting its anode (A) to ~38kHz signal yielded by D9 of the Arduino Uno (TP1) while its cathode (K) to a ~1kHz signal available at D8 of ...

Often confused with Single-Board Computers, MCUs like the Arduino series are integrated circuits designed for specific ...

Arduino has taken the product “maker” world by storm and ... The digital nature of the DDS process results in an output signal and many signal images. The images follow a sin(x)/x envelope. This ...

If you hadn’t heard of Signal before Monday, chances are you have now. The secure messaging app, available for iPhones and Android devices, has long been popular with journalists because of its ...

Rather than purchasing a universal remote he designed a system complete with infrared “babel fish” signal translator ... then uses an Arduino Nano to pass the properly translated pulses ...

Even if you don’t know what an Arduino board actually is (in which case, check out our overview), chances are you’ve excitedly shared a link with your friends about something powered by Arduino.
