Cyberpunk Voltmeter Clock

电压表时钟1.采用3个85C1型最大量程为20V电压表改装，更换2.7K电阻。也可以购买最大3V电压表，不用改装，但是表的尺寸变化了，装不到3D打印外壳内。2.采用ESP32控制器，2、4、5脚输出连接到时、分、秒电压表。使用thonny软件更改程序中的wifi名称和密码后连接自己的无线网。3.采用2节18650电池+一个5V充电模块）（模块尺寸为20*25mm）4.设计的外壳尺寸如果太大，可以自行分割打印。5.需要使用4颗M2*6螺丝固定后盖。6.需要使用12颗3*4mm强磁铁安装到底座。7.ESP32程序请到github搜索Voltage meter clock下载。Voltage meter clock1. Use three 85C1 voltmeters with a maximum range of 20V for modification, and replace the 2.7K resistor. You can also purchase a maximum 3V voltmeter without modification, but the size of the meter has changed and cannot be installed inside the 3D printed casing.2. Adopting ESP32 controller, pins 2, 4, and 5 are connected to the hour, minute, and second voltmeters for output. Use the Python software to change the WiFi name and password in the program and connect to your own wireless network.3. Using 2 18650 batteries and a 5V charging module (module size is 20 * 25mm)4. If the size of the designed shell is too large, it can be divided and printed by oneself.5. 4 M2 * 6 screws are re
