electric screw driver

Overview

The electric screwdriver I made during the summer vacation is open source here (for PCB engineering program files and 3D files, please visit https://gitee.com/yujinqu/electric-screwdriver-1-00). It uses the STC8F2K chip as the main control

It has a low-voltage alarm (VCC<3.0V) and low power consumption (current <75ua when the entire system is not working) using an N20 reduction motor with 12V 1MIN/100 rpm and a very large torque. The two buttons are forward and reverse respectively.

The low power consumption and voltage detection of program files are worth learning

MCS-51 interrupt system
For beginners, the concept of interruption is relatively abstract. In fact, the processing system of the microcontroller has many similarities with the general thinking of people. Let's take a very ap

Why can't I download the OS of WINCE60 to the development board through the network? The network is connected, the Active target device can receive it, and the development board keeps outputting BOOTME.

When MOS tubes are connected in parallel, do they have to be symmetrical?
When multiple MOS tubes are connected in parallel, do they have to be symmetrical? I saw this on Baidu. How do you calculate the current-sharing resistor?
