“嘘寒问暖”的版本间的差异

2018年5月28日 (一) 16:53的版本

概述

本作品可实现自动检测水杯温度，并通过RGB灯的颜色直观反映水杯温度的高低。使用时先根据制作说明 将作品组装完整，然后接上电源（9V电池或USB供电），打开主控板开关，将水杯放置在作品中间的温度传 感器探头上方即可。当温度高时，RGB灯亮红色；温度低时，亮蓝色；温度适中时，亮绿色。DIY动手组 装，锻炼动手能力，了解智能创意电子套件的使用，激发创新思维，增加学习乐趣。

使用教程

当水杯放置在色温杯垫上，温度感应探头测量水杯温度，并通过灯颜色反应水杯温度。当水温43℃以上，全红；当水温在43~33℃之间，红绿渐变色；当水温33~18℃之间，绿蓝渐变色；当水温18℃以下，全蓝；
