Used here to set a pin number : const int ledPin = LED_BUILTIN;// the number of the LED pin // Variables will change : int ledState = LOW; // ledState used to set the LED // Generally, you should use "unsigned long" for variables that hold time // The value will quickly ...

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...
I connected a small LED to pin 11 to see the results of the above PWM code sample. As expected, it operates at a reduced brightness due to the lower voltage. The ‘127’ is a number that can range from 0 to 255, with 255 being the brightest setting. You can use this to set the...

An additional pin (next to the IOREF pin) is not being used at the moment, but enables new functionality to be implemented in the future without needing to change the pin layout again. Discussion If the power LED does not illuminate when the board is connected to your computer, the board...
aware of the operating voltage of the Arduino pins you will use in your project. Preferably use an Arduino with 3.3V operating voltage. If you are not using a 3.3V version of Arduino, you must use a kind of 5V to 3.3V converter on RST, SCLK, SDIO and SEN (depending on your project...
