在Visual Studio 的上方,选择 "Arduino 1.6/1.9", "Arduino/Genuino UNO", "COM3" (或者其他的显示已连接 Arduino 的 COM 端口),然后按 【Build and Upload】按键: Figure 2.3 After a few seonds, the program will be built and upload, and you'll see the LED turns ON and OFF every 1 second...
Arduino代码 /* Fade This example shows how to fade an LED on pin 9 using the analogWrite() function. The analogWrite() function uses PWM, so if you want to change the pin you're using, be sure to use another PWM capable pin. On most Arduino, the PWM pins are identified with a "~...
{ // declare pin 9 to be an output: // pinMode(led, OUTPUT); pinMode(LED_PIN, OUTPUT); pinMode(LED_PIN_2, OUTPUT); pinMode(LED_PIN_3, OUTPUT); } /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() ...
UsingdigitalWrite();function LED turns to ON. IfanalogWrite();value is 255, the brightness of the LED is maximum. You can refer to the OUTPUT of the serial monitor. How do I turn Off the LED on my Arduino? UsingdigitalWrite();function LED turns to OFF. IfanalogWrite();value is 0, b...

The Arduino teaching apparatus communicates with an infrared human body induction module through Arduino and controls the turning on/off of the LED lamp based on information captured by the module, and the circuit is shown in the graph. The infrared human body induction module and the LED lamp ...
二.配置Arduino IDE环境 1.安装ESP8266开发板软件包 使用1.6.4及以上版本的Arduino, 打开Arduino IDE,打开文件->首选项在附加开发板管理器网址一栏写入: http://arduino.esp8266.com/stable/package_esp8266com_index.json添加完以后点击好。 做完这步以后重启Arduino IDE,然后依次点击工具->开发板->开发板管理器...
