On the Arduino Uno board, there’s a built-in LED. This LED is connected to pin # 13. Remember that this is an LED, so we want to set that pin to an output. This is how we will do it: void setup() { // put your setup code here, to run once: pinMode(13, OUTPUT); } ...

一套Arduino,最好是 Arduino Mega,但是 Arduino Uno 也可以。 一台Windows 电脑,最少需要 4GB 内存及 100GB 硬盘,操作系统需要Win7 或以上。 1.1 Arduino IDE Selection 1.1 Arduino IDE 的选择 To write programs to control an Arduino board, we need an IDE. The official IDE can be found in the ...
Different types of Arduino board have different numbers of interrupts pins e.g. Arduino UNO have two interrupt ports and Arduino Mega2560 have six interrupt ports named as INT1,INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be e...
与 GPIO 章节一样,第一个程序是 Hello World 的硬件版本——一个闪烁的 LED。加载程序后,您将了解更多关于编程、其结构以及如何使用它的知识。在GPIO 章节中,我们构建了一个带 LED 的小电路。然而,Arduino 有一个内置在电路板上的 LED 供我们使用,所以我们还不需要打开试验板。LED 与 UNO 上的 13 号插脚...
After you’ve started the IDE, go to the File→Examples menu and select 1. Basics→Blink, as shown inFigure 1-7. The code for blinking the built-in LED will be displayed in the Sketch Editor window (refer toFigure 1-6). Before the code can be sent to the board, it needs to be...
16 (LED-) This pin is used with pin 15(LED+) to setting up the illumination of back light of LCD. This pin is connected with GND. Commonly Used Command Code In the first example code, you don't need to care of this.. just calling a couple of function is enough. However, if ...
The code below written for Arduino UNO i think hence the pin attachment. For mega it would be at: Arduino Mega double pin layout Code: /* SD card file dump This example shows how to read a file from the SD card using the SD library and send it over the serial port. The circuit: ...
