でもまぁ16MHzのArduino R3ではこれが限界値ということで納得はできました。 USB電源ではそれなりにノイズはありますが、電池で駆動すれば残留ノイズは十分に低く、10ビットADC、サンプリングレート31.25kHzとは思えないくらいクリアです。

This project is designed to test the speed of the DAC (Digital-to-Analog Converter) and ADC (Analog-to-Digital Converter) on the Arduino UNO R4. Open the R4_DAC_ADC_Speed_Test.ino file in the Arduino ...

One of the great things about the Arduino environment is that it covers a wide variety of hardware with a common interface. Importantly, this isn’t just about language, but also about abstracting away ...

This simple project demonstrates how to use the Arduino Uno to convert an analog signal into a digital value and display the result on the Arduino IDE's serial monitor. The analog input is generated ...

Using the Arduino ADC and DAC features to realize a full-fledged multichannel anayzer with only a few common components allowed to operate a used NaI scintillation counter (from Ebay) and compare the ...

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, ...
