BlinkM 需要连接到5V, GND, 和Arduino的I2C SDA 和SCL 代码 /* * RosSerial BlinkM Example * This program shows how to control a blinkm * from an arduino using RosSerial */ #include "WProgram.h" //include the Arduino library #include <stdlib.h> #include <ros.h> #include <std_msgs/...
The second code example is a little more interesting as it switches that pin on and off every 1,000 milliseconds (1 second). The orange LED will blink at one-second intervals…or will it? voidsetup() { //The following code will be executed once when your Arduino turns on. ...
void setup() { pinMode(13, OUTPUT); //set pin 13 as output attachInterrupt(digitalPinToInterrupt(pin), blink, CHANGE); //interrupt at pin 2 blink ISR when pin to change the value } void loop() { digitalWrite(13, state); //pin 13 equal the state value } void blink() { //ISR ...
Blink : Turn an LED on and off. 闪 烁:开启LED的开启和关闭。 DigitalReadSerial: Read a switch, print the state out to the Arduino Serial Monitor. DigitalReadSerial:阅读交换 机,打印到Arduino串行监视器的状态。 AnalogReadSerial: Read a potentiometer, print it's state out to the Arduino Serial...
B− Used to upload a program to the Arduino board. C− Shortcut used to create a new sketch. D− Used to directly open one of the example sketch. E− Used to save your sketch. F− Serial monitor used to receive serial data from the board and send the serial data to the ...
Step 6.Click theUploadbutton to upload the Blink example code to the board. Once uploaded, you should be able to see the pin 25 Green (USER) LED on the board blinks once a second. If it does, congratulations! This means the connection is successful and now you can explore more projects...
Source code containing computer instructions for controlling Arduino functionality is usually referred to as asketchin the Arduino community. The wordsketchwill be used throughout this book to refer to Arduino program code. The Blink sketch, which comes with Arduino, is used as an example for reci...
Blink- Turn an LED on and off. DigitalReadSerial- Read a switch, print the state out to the Arduino Serial Monitor. Fade- Demonstrates the use of analog output to fade an LED. ReadAnalogVoltage- Reads an analog input and prints the voltage to the serial monitor. ...
