2.3 编写第一个程序 The setup() function will be run once, when the Arduino is powered on, or the "reset" button on the Arduino board is pressed. 当Arduino 开机时,或者是 Arduino 的【Reset】按键被按下是,程序里面的 【setup()】函数,将会被运行【一次】 The loop() function will be looped...
if(!buttonActive && clickFlagMenu) { // Was B:MENU button pressed? buttonActive = true; // Set button flag deBounce = millis() + DE_BOUNCE; // and start debounce timer menuLoop(backColor); // Execute menu routine until finished clickFlagSelect = recordingInProg = false; // Clear unne...
setHoldTime(unsigned int time) Set the amount of milliseconds the user will have to hold a button until the HOLD state is triggered. 设置用户必须按住按钮直到触发HOLD状态的毫秒数。 setDebounceTime(unsigned int time) Set the amount of milliseconds the keypad will wait until it accepts a new key...

Anyway, after those problems are sorted out, I got my Arduino to play a sound when the button is pressed. My test sound clip wasfrom the game Portal 2: the ecstatic “SPAAACE!” emitted by the corrupted Space Core when it finally got its wish to go flying through space. ...
New in version 2.0: Let's you know when the key has changed from one state to another. For example, instead of just testing for a valid key you can test for when a key was pressed. setHoldTime(unsigned int time) Set the amount of milliseconds the user will have to hold a button ...
We'll demonstrate this by adding a button to our circuit as shown below:The code below will check the button state on each pass of the loop. Led1 and sweeper2 will not be updated when the button is pressed.Copy Code #include <Servo.h> class Flasher { ...
Checking if a button is pressed (we will refer to this as the button state) on an Arduino entails reading the state of the pin that button is connected to. If the state is ‘HIGH’ then the button is being pressed, if it is ‘LOW’, then it is not being pressed. This is achieved...
