OLED模块为OLED显示屏+PCB+铁框构成。 OLED显示屏是指有机电激发光二极管（OrganicLight-EmittingDiode，OLED）由于同时具备自发光，不需背光源、对比度高、厚度薄、视角广、反应速度快、可用于挠曲性面板、使用温度范围广、构造及制程较简单等优异之特性，被认为是下一代的平面显示器新兴应用技术。 发光原理： 有机发光显示技术由非常薄的有机材料涂层和玻璃基板构成。当有电荷通过时这些有机材料就会发光。OLED发光的颜色取决于有机发光层的材料，故厂商可由改变发光层的材料而得到所需之颜色。有源阵列有机发光显示屏具有内置的电子电路系统因此每个像素都由一个对应的电路独立驱动。

使用Arduino，OLED显示屏和AD9833 DDS模块为您的实验室创建有用的波形发生器。 硬件部件: Arduino Nano R3 × 1个 显示SH1106 I2C Oled 128x64像素（4针）× 1个 AD9833 DDS模块× 1个 5V继电器模块（可选）× 1个 电容10 µF × 1个 电容10 nF × 1个 AC-DC 100-220V至5V降压电源模块× 1个 手动工具和制造机: 烙铁（通用） 特征 输出频率在1 Hz至999999 Hz之间 频率变化的两种模式:对数和一位数字 波浪，正弦波，三角形和正方形三种类型 交流或直流输出耦合 在两个预定义的频率值之间连续扫描的能力 仅由一个旋钮控制 集成的屏幕保护程序可以保持OLED显示屏的使用寿命 1kHz正弦波: 1kHz的三角波: 1kHz方波: 注意 DDS模块的输出幅度不是很高，正弦波和三角波的峰峰值平均在550 mV至650 mV之间，对于方波，峰峰值平均约为4.5V，约为峰峰值4.5V。当然，这往往会与频率成反比地下降，但高达1MHz时，它是线性的。AD9833 DDS模块能够产生高达12 MHz的信号，这对我来说不是必需的。如果您需要超过1 MHz，则可以尝试进行实验，并在显示屏上添加一个或两个数字，但这需要对图形界面进行部分重新设计。 输出信号的质量还取决于电源的质量，因此最好使用线性电源，而不是像切换电源那样，以减小从旧项目中恢复的情况的大小。但是，即使使用开关模块，波形的线性度也相当好。 快速参考 原型 我使用了具有10A触点的预组装继电器模块，因为目前我还没有微型簧片继电器，当不需要功率继电器时，这将是避免使用晶体管二极管和电阻器的最佳选择。Arduino数字PIN最多可提供40 mA的电流，因此您不能直接将机电继电器与120/150欧姆线圈连接。 使用电源时务必非常小心！
