在本文中,我们将学习使用著名的 Arduino-Nano 板构建电池容量测量电路。我为浸入式组件设计了 PCB 板。因此,即使是初学者也可以焊接和使用该设备。 示意图 印刷电路板 材料清单 Arduino代码 #include #include 常量 浮动Low_BAT_level = 3.2 ; //3R 负载 (R7) 的电流步长 const int Current[] = { 0 , ...
If you are on a tight budget you can explore the Chinese alternative Arduino Nano Every which will cost you a max of 5 USD. You will hardly notice any difference between the official Nano Every and the one you got from the Chinese manufacturers. Conclusion The Arduino Nano Every is the up...
3.5 #define #define 是一个很有用的 C 语法,它允许程序员在程序编译之前给常量命名。在 Arduino 中,定义的常量不会占用芯片上的任何程序内存空间。在编译时编译器会用事先定义的值来 取代这些常量。 然而这样做会产生一些副作用,例如,一个已被定义的常量名已经包含在了 其他常量名 或者变量名中。在这种情况下...
Only protect the expensive electronics such as Nano, IMU and pixels. In this case we can use pretty much any P-MOSFET available as it would only need to supply up to 300mA of current at max. For now I though we could at least protect the main electronics, which will make life a bit...
