（垃圾桶由超声波感应自动开启，延时后关闭）


（垃圾桶的所有布线全部精细的设置在桶盖，桶身完全没有布线，轻松取开，倒垃圾无忧）


（内置的时钟可以为你精准报时，LM35温度传感器也可以尽可能准确地告知你温度信息）

别看这个垃圾桶看起来非常的小巧和简陋，但可谓是麻雀虽小，五脏俱全，当你伸手放在桶盖前时，桶盖会自动感应打开，而这种识别方式则是双通道超声波传感器的功劳，这一传感器听起来非常的高大上是不是，事实上价格也是非常的便宜，一般不会超过10元。
垃圾桶桶盖上有两个小按键，右侧按键是用来选择功能模式，而左侧按键则用来进行确认，简洁而实用，垃圾桶内内置蜂鸣器和RTC时钟模块，可以进行精准定时和报时。LM35提供的温度数据使得垃圾桶摇身一变成为了温度播报员。桶盖上USB接口也大大拓展了使用者的想象空间，它可以用来充电，用来照明，用来驱动小风扇等等。当夜幕降临，桶内内置的LED小夜灯可以将垃圾桶摇身一变成为可爱的小精灵，在寂静的黑夜中发出温暖而和蔼的光芒。

看了这些，你想拥有这样一款智能又可爱的桌面垃圾桶吗？别急，接下来我就要向你们分享这个智能垃圾桶的所有奥秘。

首先是硬件方面，制作智能垃圾桶，我们需要哪些原材料呢？

1.普通桌面垃圾桶一个，某宝上价格5到8元不等

2.小型舵机一个引脚的棕、红、橙线以此对应（GND，VCC，信号线）

LM35温度传感器

3. 0.96存OLED显示屏，价格一般在10到15元之间

4.三种0805型号贴片LED灯（白，蓝，绿），颜色可以根据个人喜好而定哈

5.轻触按键两个

6.usb接口模块

7.DC电源接口模块及电源线


8.RTC时钟模块

9.超声波模块一个

10.Arduino NANO单片机最小系统板一块

这样一来我们的硬件准备阶段就告一段落啦，接下来就要进入动手制作环节

步骤一：剪去桶盖上的犄角，使得桶盖能够进行更大扭矩的转动，防止因为垃圾桶盖转动不足导致开口过小，投不进去垃圾

步骤二：在桶盖上挖出大小合适的通孔，使得超声波模块的“小眼睛”、OLED、USB接口、DC电源接口和按键能够嵌入桶盖，挖孔工具可以是钻机，电烙铁或是激光切割


步骤三：按照所给PCB线路图进行连线

步骤四：曲轴连杆式传动结构的制作，选用硬质杆与舵机臂组成连杆传动机制，控制桶盖的开合，这样的硬质杆可以由身边许多的东西替代，比如排针，牙签，甚至热熔胶棒

步骤五：利用Arduino IDE和usb串口给Arduino下载程序。Arduino IDE的配置要选择为Arduino NANO MEGA328P，并选择好相应的串口，这样才能成功的将程序烧录进单片机

当程序成功载入ArduinoNANO上时，你就将拥有这样一款超级拉风的多功能桌面垃圾桶了
还在等什么，赶紧动手试一试这个简单而炫酷的DIY吧！
