2mm厚的3030cm硬纸板确实很难剪,所以如果有条件的话,还是直接买现成的道具比较好。💻我使用的是UNO R3板子和Sharp IR Distance Sensor传感器。传感器的数据还算稳定,连接调试和代码也比较简单,属于Arduino的入门级别。不过有一点需要注意,这个传感器在没有连接电源的情况下也会给出正常的数据。我最开始尝试的时候,5V...

我们将在IR 传感器和 Arduino之间建立一个接口。IR Proximity Sensor的工作原理很简单,它有一个 IRLED和一个光电二极管,IR LED 发出 IR 光,如果有任何障碍物挡在发出的光的前面,它就会被反射,并检测到反射光由光电二极管。但是反射产生的电压会非常低。为了增加它,我们可以使用运算放大器比较器,我们可以放大并获得...
