今回は、Arduino UNO R4を使ってAD変換をする方法をご紹介します。 アナログ入力電圧をデジタル値に変換し、そのデジタル値から電圧に換算することで、入力電圧を推定できます。 Arduino UNOは電源電圧の5Vまでをアナログ端子に入力できます。 Arduinoは10ビット ...

This is usually done by simply checking the range of the input argument, so in the case of the Uno the analogRead() function would have something along the lines of ...

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 ...

In this tutorial we are introducing concept of ADC (Analog to Digital Conversion) in ARDUINO UNO. Arduino board has six ADC channels, as show in figure below. Among those any one or all of them can be ...
