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 ...

I'm using BBC microbit v2 and I noticed that the analogRead function always gave us 0 (trying to read from a microphone). In the file wiring_analog_nRF52.c, in the function analogRead , the variable ...

I don't appear to have much luck with pins A8 - A11. I am using Arduino Mbed OS Giga Boards v 4.4.1 To enable the program to compile, I have copied the pure_analog_pins.cpp and pure_analog_pins.h from ...

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 ...
