简单修改一下电路板,我们就可以把LED连接到Arduino的输出插脚上。将红色跳线从Arduino 5V接头移动到D13,如下图所示: 现在载入第1课中的“眨眼”示例。你会注意到内置的“L”型LED和外部的LED现在都应该闪烁了。 /* Blink Turns on an LED on for one second, then off for one second, repeatedly. This e...
// Turn On an LED void LEDOn(int intLedNo); // Turn Off an LED void LEDOff(int intLedNo); // C11 - Motor Related functions // Move a Single Motor // intDir: 1 or -1 // intSpeed: 0 to 255 void Move(int intMotorNo, int intDir, int intSpeed); // Stop a Single Motor ...
In this Arduino tutorial I will show you how to turn an LED on and off with a push button. In fact, we’ll do 2 slightly different applications. First, we will power on the LED when the button is pressed, and power off the LED when the button is not pressed. And then we’ll mo...
