Arduino IDE automatically installs these tools, but in this case the tool is not present at the path where it should be installed: C:\Users\Robert Faass\AppData\Local\Arduino15\packages\builtin\tools\serial-dis
主要有三种方法： 1）使用回调函数Callback，它提供了一个函数来把返回值传回给JavaScript。
The second step is to connect your Arduino to a computer via a USB cable and launch the Arduino IDE. Head to theToolsmenu and hover over ‘Port‘ to see if your Arduino was detected. If not, follow the link in the paragraph above for more information. However, it is likely that the...
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,都会记录下来—小小的进步或是搞不掂的问题,希望能够抛砖引...
