LCD具有两个独立的电源连接;一个(引脚1和2引脚)用于LCD本身,另一个(引脚15和16引脚)用于LCD背光。将LCD上的引脚1和16连接到GND,LCD上的引脚2和15连接到5V。 绝大多数LCD都具有用于LED背光的内置串联电阻。如果您碰巧有一个不带电阻的LCD,则需要在5V和引脚15之间加一个。 要计算串联电阻的值,请从数据手册中...

打开示例文件夹。 Arduino可以运行几个示例代码。连接LCD并测试一些例子。 代码 您必须添加库然后上传代码。如果这是您第一次运行Arduino板,请不要担心。只需按照以下步骤操作: 访问www.arduino.cc/en/Main/Software下载您的操作系统软件。按照说明安装IDE软件。
(i.e.CL2is ignored whileCL1is up, etc...), so maybe this code can be adapted to other controllerless modules. Module's datasheet is necessity for the connector pinouts and timing requirements. Some modules may even generate LCD drive voltage internally, and outputting it on a pin so ...
