步骤1:注册指纹并连接FPS传感器和LCD 请遵循adafruit教程http://www.adafruit.com/product/751中的说明,了解如何在注册过程中将指纹传感器连接到arduino。下载适用于Windows的软件并安装在您的计算机中。使用该软件注册指纹使该过程更加容易。 请确保将adafruit库添加到您的arduino库中。 转到http://arduino.cc/zh-CN/...
Intro To Arduino 16x2 LCD PIC Interface 16x2 Custom Characters Take a look at the above articles before continuing to read this article.Whenever you're learning how to use a new system, in this case an Arduino, it's very important to put a good amount of effort into learning how to ...
In this tutorial, you will learn how to interface LCD with Arduino. We will be using Arduino Uno, but the same code and concepts work for other Arduino development boards also. Firstly,16×2 LCDinterfacing with Arduino will be discussed. After that, we will also provide examples of 16×4 ...
在连接液晶显示屏到你的Arduino板之前,我们建议到焊接一组排针到LCD显示屏的连接器上(14或者16引脚数),你在上面的图可以看到。 液晶显示屏连接到电线板,连接引脚: LCD RS pin to digital pin 12 LCD Enable pin to digital pin 11 LCD D4 pin to digital pin 5 LCD D5 pin to digital pin 4 LCD D6 ...
