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 ...

This DIY gas leakage detector is designed for educational and basic monitoring purposes. For critical safety applications, ...

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 ...

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 ...
