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...
Metro - help you time actions at regular intervals MsTimer2 - uses the timer 2 interrupt to trigger an action every N milliseconds. OneWire - control devices (from Dallas Semiconductor) that use the One Wire protocol. PS2Keyboard - read characters from a PS2 keyboard. ...
