Load Arduino Uno R3 with sketch in HP8596E_Print_Arduino. The pinout and wiring of Arduino to D-SUB connector is described at the top of the sketch. Beware: If you decide to change the mapping of the ...

One way to address noise on analog signals is to take multiple readings and average them out, but the way that we do this depends on where the noise is originating in our system I always hoped to be ...

Satisfies a need in my electronics lab: There are plenty of fantastic spectrum analyzers out there, and most of them have a bottom end of 100 kHz (or higher). That should be my top end (need to see ...

Everything you wanted to know (but were too afraid to ask) about using the MSGEQ7 audio spectrum analyzer chip. I’ve talked about using the MSGEQ7 Spectrum Analyzer chip in several columns over the ...

[El Artis] just finished building an audio spectrum analyzer that uses a character LCD. The uses an Arduino to drive the display, but unlike other meters that use the microcontroller for analysis, [El ...
