In the loop, we make the output of the led HIGH (5v), wait 1,000ms, make it LOW (0v) and wait for another second. This loop will be repeated forever (at least until you restart the Arduino, or upload another program) /*this is a comment */ this is not this is not a comment...

Background rendering of LEDs so that your program/sketch can prepare the next frame and respond to user input without affect frame rate. In addition to writing to the LEDs, this library also includes a number of functions for high-performing 8-bit math for manipulating your RGB values, as ...
The easiest way to install the Windows drivers for the Arduino controller is simply to plug the controller into your computer and wait for the Found New Hardware Wizard to appear. You may need to open the Device Manager, as shown in Figure 4-3. Figure 4-3. Selecting devices Continue to ...

为此,首先必须将模式设置为输入。int buttonPin = 3; int val; pinMode(buttonPin, INPUT); val = digitalRead(buttonPin); 这段代码片段将值 3 赋给buttonPin变量,我们创建一个变量来存储结果。然后,它将引脚模式设置为输入,以便我们可以读取它。最后,我们将引脚 13 的值读入val变量。
37款传感器与执行器的提法,在网络上广泛流传,其实Arduino能够兼容的传感器模块肯定是不止这37种的。鉴于本人手头积累了一些传感器和执行器模块,依照实践出真知(一定要动手做)的理念,以学习和交流为目的,这里准备逐一动手尝试系列实验,不管成功(程序走通)与否,都
