So far in our discussion of programming the Arduino microcontroller, we have generally glossed over the physical interactions of turning things on and off and sensing the world around us that make programming microcontrollers so much fun. Now it’s time to fix that. Programming a microcontroller ...

arduino digital input 数字电路 按键 分类:Arduino 今天我们借助一个按键开关来聊一下有关Arduino“数字写入”的问题,众所周知开关就是可以控制某段电路断开或接通的元件,但是怎么能通过一个按键开关控制Arduino某一数字接口的电位呢?让我们来用按键连接一个正逻辑电路(如下图),10K电阻接地,按键开关连接+5V,公共端与...

On a Wiring module or an Arduino module, you declare the pin to be an input at the top of your program. Then you read it for the values 1 or 0, like so: // give the pin numbers names: const int inputPin = 2; const int outputPin = 3; ...
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...
