pinMode(2, INPUT_PULLUP);pinMode(3, INPUT_PULLUP);pinMode(4, INPUT_PULLUP);pinMode(5, INPUT_PULLUP); 下面的代码块用于在按下按钮时播放歌曲。它读取每个按钮的数字值,当它变低(零)时,它假设按钮被按下并通过调用所需的函数播放相应的音调。
Fix: change project build settings on error would disable theChange Buildbutton and not re-enable it when build settings were changed. Fix: clean up and refactor code. 1.4.0 Add: UI for changing Arduino build board, cpu, programmer, etc. Under Tools > Arduino Support > Change build setting...
configuration with the internal Arduino pull up resistor, the button is pressed. When we detect this, we can decide to do any action we want. And if the condition is false, which means that the state is HIGH (because there are just 2 possible states), we know that the button is not ...
As for the final problem of running just once (immediately after upload) on an Arduino Nano 33 BLE Sense, I don’t have any hypothesis. My ESP8266 happily restarted this test sketch whenever I pressed the reset button or power cycled the system. I’m going to chalk it up to a hardware...
