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

This is called from an interrupt and should finish as fast as possible. The only thing you should add here is a directly connected encoder. All I2C key methods are strictly forbidden. They take to much time to be run inside the interrupt. You can add 1-2 directly connected push buttons ...
