INPUT 输入模式 OUTPUT 输出模式 INPUT_PULLUP 输入上拉模式 Blink程序中使用到的pinMode(LED_BUILTIN, OUTPUT): 即是把LED_BUILTIN(13号)引脚配置为输出模式 配置成输出模式后,还需要使用digitalWrite() 让其输出高电平或者是低电平。其调...

For most applications, however, this is more than enough. The pins of the processor connect to the headers, and you can connect them to virtually anything you can imagine. You just need to write some lines of code to control them. The I/O pins (Input/Output) can be used as input ...
This article describes my version of digital input/output functions for Arduino, which work faster than the 'built-in' functions while remaining as easy to use and portable as the original ones. If you just want to try the new functions, feel free to go directly to "Using...
