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 ...
The ATMega328 microcontroller as mounted on the Arduino UNO board has a 10-bit AD converter. Let’s use its function analogRead to measure some voltages with. How can we improve the accuracy of the ...
Using the stock variant for the F030F4 HSE 8MHz, when using analogRead always returns 0 if the usart is disabled, if the option "enabled (generic serial)" is selected the analogread returns the ...
Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...
