2021宁德五中创客作品创作方案05
项目作品案例名称：《基于Arduino的智能汽车头灯》
作品案例类别：创意智造
学校：福建省宁德市第五中学
作者：林立凡 高二（8）
指导教师：邬肖英
涉及学科或专业领域：Arduino、超声波、激光切割
项目作品概述（请填写）
该装置要实现的功能为：
超声波测量洗车前方障碍物距离，在OLED屏中显示；
LED灯模拟汽车头灯，前方有障碍物或人，车灯亮度减弱；
当车前方有人，距离10cm（模拟），汽车车灯减弱，并蜂鸣器报警；
驾驶员也可以手动控制灯的亮度。
二、主要材料
核心部件：Arduino NANO 开发板、I/O扩展板
传感器：HC-SR04超声波模块、模拟角度传感器
执行器：蜂鸣器 LED灯珠
显示器：0.91寸 白色 OLED显示屏模块128*64液晶屏 4针

四、作品设计的体会
设计源于生活，又服务于生活，人们的生活离不开设计，设计也离不开生活给予的灵感，所以说设计与我们的生活息息相关。这次设计我们收获很多、学会很多、比以往更有耐心很多。希望我们的产品能真正应用到人们的实际生活中，给人们的生活带来方便，保障人们的安全。
