按钮通过更改Arduino“看到”的电阻来工作。 Arduino引脚通过一个10k欧姆的电阻器(“下拉”电阻器,确保该值保持较低),将开关直接接地( LOW )。按下按钮后,在没有电阻( HIGH )的情况下,电路看到的值将变为+ 5v。 Arduino可以使用 digitalRead(pin)命令检测到此更改。将按钮连接到Arduino数字输入/输出(I/O)上的...

所以也就不存在因为NODEMCU没5V而建议买D1 MINI,实际上来说吧D1 MINI倒是很便宜,而且同样基于ESP8266且带串口转USB,我的意见是如果将来打算好好玩ARDUINO,买个D1标准版18包邮也不是不行,除非对体积有特殊要求的场合,不然ARDUINO还是买标准版比较好

Between e.g. the Arduino Micro, Arduino Nano, RP2040 (RPi Pico), I wanted to use a Micro, but only had a Nano lying around, so made one with a DIN MIDI output instead of USB-MIDI. The potmeters are all 5kOhm, so putting them across Vcc and Gnd is fine (dissipates 1mA ...
There are some great projects out there that describe how to output MIDI from an Arduino board (see References below), but these require additional hardware (e.g. MIDI modules, MIDI interface, etc). Since most people don't have extra MIDI hardware, I decided to just write some software ...
I am new to Arduino and building electronic circuits and have a small MIDI project I am undertaking with an Arduino UNO. I have built a basic MIDI input and Output circuit on a breadboard and I am using the Arduino MIDI library. Tested using the example callback sketch provided in the ...
http://fortyseveneffects.github.io/arduino_midi_library/ Using MIDI.begin In the setup() function of the Arduino, you must call the MIDI.begin() method. If you don't give any argument to this method, the input channel for MIDI in will be set to 1 (channels are going from 1 to 16...
