MAKER:Giannis Vasilakis／译：趣无尽 Cherry（转载请注明出处）
本次教程介绍一款从原理图、PCB、源码、3D外壳图纸齐全的开源小项目，小巧实用的生态缸光照系统。该项目是基于 Atmega328p 微控制器和 Arduino 制作，很适合拿来练手。

功能特性：
1、支持通过串行监视器设置系统时间。
2、通过编程控制光照时间和颜色。

观看视频，感受一下灯光的实际效果：

下面罗列了主要的部件和资源，具体的 DIY 操作步骤不再赘述，如有问题欢迎在「趣小组」（https://talk.quwj.com） 交流。

编程

用五根线将 TTL 转 USB 模块与 PCB 上的TX、RX、RS、GND、5V相连，其中引脚 RX 和 TX 必须交叉连接。
注意：如果你使用的是 Arduino UNO，请先从板子上取下 ATmega328 芯片，然后将板子的 RX 接头连接到 RX 引脚，将 TX 接头连接到 TX 引脚。 RS 引脚必须连接到 Arduino UNO 复位引脚。
