项目介绍

在这个项目中,我们将使用微控制器制作动态LED效果。它的产出有无数种可能性,我们也可以将它与其他项目结合,拓展出不同的作品。这个教程将重点介绍如何使用Arduino Uno微控制器和不同的代码来实现不同的LED效果。

我们可以从阅读这个简短的arduino指南开始,这里是中文版:)

这个入门指南解释了如何通过下载IDE(Integrated Development Environment集成开发环境)软件来初始化你的控制板。我强烈建议你仔细阅读它,以避免在后续流程中出现问题。

在这个项目中,我们使用的是Arduino UNO,这是最常用的arduino控制板之一,售价为23刀。因为arduino是开源的,所以有很多仿制板。它们的价格更便宜,几乎与正版的工作原理相同,但是有时候会出现一些质量问题。

代码样例

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}
