推力采集卡

代码放最后 AWA 代码有点长,所以放在了最后 : )

材料表(主要材料)

序号名称
规格
1ESP32开发板看着买
2HX711模块推荐买紫色或红色款的
3继电器3V/5v  5/4引脚 建议不要买常开型
4蜂鸣器无源
5TF卡模块

带电平转换芯片

本采集卡使用ESP32 作为主控 arduino进行开发

明天开学力,电脑要没收了 : (

祝大家开学快乐 : )

拆解前

由于我没有3v的继电器,所以弄了个升压板,如果购买的是3v/5v继电器就可以不用了 : )

由于继电器有4角5脚的,常闭,常开的,所以在接继电器的时,要看好下图的接线图,图中举出了3种继电器接线方法,接线时 请认真看好,否则可能出现上电就点火的危险情况!!!认真看好!!!

接线图(手画的 不太好 见谅)
