0x00 前言说明

这几天在淘宝买了esp01s,一个带esp01s的wifi中继准备做一些IOT(物联网)实验。踩了好多坑,终于成功点灯了!下面录几张实验的照片吧~

0x01 实验拍照

这是一个简单的实验,esp01s接面包板,1k电阻,led灯(1k电阻主要用来限流)。

这是拆一个空调遥控器,用电池点亮led灯。本来是给继电器供电的,后来发现这个电池只能输出3v,继电器需要5v。

image

于是我用了一个usb电源(最好不要用带数据传输的usb线,要选择只能供电的线),切断线,插上继电器,就成功点亮了!Ps:之前这里可能是线路暴露太久导致短路冒烟。我吓了一跳,不过还能用~

期间还拆了家里的开关哈哈(记得关着大门拆)
