但是,我们将在简单的分压器设置中使用LDR来生成要检查的信号,以便生成的波形将根据LDR周围的光强度描述电压电平。 按照下面的原理图连接组件; 连接后,设置应如下图所示。 完成所有连接后,我们可以继续编写代码。 ArduinoOsclloscopeCode 我们将为这两个部分中的每一个编写代码。对于前面提到的绘图仪,我们将编写一个...
The sketch is based on the LED blinking code from the previous recipe, but instead of using a fixed delay, the rate is determined by a light-sensitive sensor called a light dependent resistor or LDR (see Recipe 6.2). Wire the LDR as shown in Figure 1-8. Figure 1-8. Arduino with lig...

For example a microcontroller can be programmed to read light sensor LDR continuesly and display the light intensity in a LCD. When light intensity falls below certain level it might trigger a relay unity which switches on lights. But all of these logic runs in a single loop. However there ...
