描述

步骤1:零件清单

Arduino

对于此项目,我们需要:

TCS34725 RGB颜色传感器对于Arduino by DFRobot

带有RGB字体显示的I2C 16x2 Arduino LCD DFRobot

DFRobino的DFRduino Pro Mini V1.3(8M3.3V328)

2 x CR2032电池座

滑动开关

RGB LED模块

电线

3x7 cm原型PCB

男性和母针头

2x M2x20螺丝和螺母

工具:

3D打印机,如果你不拥有它,你可以从Shapeways获得印花盒

菲利普斯螺丝刀

烙铁

焊接

步骤2:原理图

Arduino

请参阅下面打开视频的装配部分和示意图,了解如何

使用上面提供的原理图进行正确接线。

2》

在测量完零件后,是时候设计一个3D外壳并进行打印了!

设计

以下是我在tinkercad上的设计链接:https://www.tinkercad.com/things/dG47Pr28uwx

上面的内容设计非常适合上面列出的所有组件。

前部将固定LCD屏幕和颜色传感器。

主要的3x7 cm PCB将容纳DFRDuino Pro Mini,电池座和3个按钮,将是从内部拧到后部。

RGB LED将位于后部顶部内部。

电源开关将安装在后部的小孔中。

打印

准备打印的3D模型是av适用于Thingiverse:https://www.thingiverse.com/thing:3223709

打印设置可能因打印机而异。

电池盖部件和前部需要支撑因为前部有一个内置的距离,可以提供颜色传感器和样品之间的距离。

如果你没有3D打印机,你可以从Shapeways获得印刷品:点击这里

汇编

有关汇编说明,请参阅开头提供的视频的汇编部分。

第4步:源代码

GitHub上免费提供源代码:https://github.com/alojzjakob/Arduino-Color-Picker

非常欢迎您改进代码,因为提供的代码只是起点,但效果很好。

这个项目使用这两个特定的库,所以一定要把它们添加到你的Arduino IDE中:
