下面的代码用一个for()循环开始来设计数字引脚pin2-7作为6个LED灯的输出。 在代码的主循环里,两个for()循环用来逐渐循环LED灯,一个接一个,从pin2-7。一旦pin7被点亮,程序就会反过来,倒着点亮每一个LED灯。 /* For Loop Iteration Demonstrates the use of a for() loop. Lights multiple LEDs in sequence...

Arduino Traffic Light Code It’s now time to write some code to bring our lights to life. If you have programming experience, then you will find this code really basic. If you’re new to programming, then this is a great way to start learning all the basics. First, we will need to...

LED (WS2812) strip in a 50mm circle. Around the camera there are 8 more, so this makes 26 total. Every 30ms the lighting is changed. So each of these 26 lights are on one at a time, then all bottom lights, then all top lights. So 28 different lighting combinations. It's pretty...
This is a simple project and is great for introducing yourself to more of the basics of the Arduino. Much like the Arduino traffic lights project this project uses a variety of LEDS and resistors to make up the circuit. We will also be using a physical switch to tell the Arduino when ...
This isn’t a great impediment, and you should purchase a prototyping board anyway for doing any kind of serious work with the Arduino controller. Figure 4-8. Arduino Mini and Programmer The Uno comes with small LED lights that you’ll find next to the USB port on the Uno. When you ...
