转速表原型机成功运行The rev counter prototype is up and running
➀ 基于Arduino Pro Micro的数控车床转速表原型机在信号发生器上运行精准，但机械抖动导致±3计数误差；
➁ Arduino的8位PWM分辨率限制引发定制化10位代码开发需求，并设计电位器安全机制防止电机误启动；
➂ 通过3D打印部件和开源代码实现硬件/软件迭代，为车间应用提供解决方案。
➀ A rev counter prototype for a CNC lathe using Arduino Pro Micro faces jitter (±3 counts) due to mechanical imperfections but functions accurately on signal generators;
➁ Limitations in Arduino's 8-bit PWM resolution (via analogWrite()) prompt plans for custom 10-bit code, while a safety feature prevents unintended motor activation;
➂ 3D-printed housings and open-source code highlight iterative hardware/software integration for workshop deployment.
