Components for the digital input exercise: 1. Breadboard, 2. Switch, 3. Arduino Uno 在Arduino IDE 中创建一个新的草图,我称之为我的 chapter_01_2,并复制清单 1-3 中的代码。验证并将代码上传到 Arduino。当您按下按钮时,Arduino 上的 LED 应该会亮起。 int buttonInput =2; intLEDOutput=13;void...
The second line of code transmits ‘Hello World’ via the serial port (in this case, it will pass through the Arduino’s serial-to-USB interface so your computer can read it). This mean the serial port’s output is being piped to the USB port, and then to your PC....
// initialize serial communication at 9600 bits per second: Serial.begin(9600); // make the button‘s pin an input: pinMode(button, INPUT); // to print first value of count_presses which is 0 Serial.println(count_presses); } void loop() { // read the button input pin: int button...

Serial.println("Hello,World"); delay(1000); } RGB LED Pin 11 is the enable pin of RGB LED. You can light up the RGB LED by setting the Pin 11 high. Here we are going to make it go flash. First, we need to add a third-party library. ...

This function allows us to print a line to the Arduino serial monitor. You will notice this will print the text and then start on a new line for the next input or output. void setup() { pinMode(redLedPin, OUTPUT); Serial.begin(9600); while (! Serial); Serial.println("Enter Y to...
*Similarly, we also have a Pull-Up resistor connection there we connect a resistor between the input and 5V. Block Code *In the forever section as you can see I have taken a read digital pin block, set it to read pin 2 and print the value on Serial Monitor. ...
