The Arduino Uno, also known as Genuino Uno, is more than just a board; it’s an open-source gateway to the world of electronics and coding. Its heart, theAtmel ATmega328Pmicrocontroller, is your perfect companion for diving into the essentials of embedded programming. There are several rea...
Instead from the Arduino Uno schematics we can find out where the pins are connected, for example we can find that the LED is connected to the PB5 pin of the Atmega328p chip, so that’s the pin we need to control. Now we need to write the code that toggles the PB5 pin. The ...

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 ...
For example: attachInterrupt(digitalPinToInterrupt(2), InterruptFunction, Low) ; Example code of how to use Arduino interrupts Below the example code of LED blinking in which the interrupt function is used to understand more clearly. const byte ledPin = 13; ...
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 号插脚相连;其他版本可能会有所不同。从编程菜单中打开 Arduino IDE。 验证板已连接并被检测到。 在Arduino IDE 菜单上,转到工具并将鼠标悬停在电路板...
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...
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: ...
