Electric screwdriver 1.2

Overview

This is the third version of the screwdriver I made. Seeing that many people cloned my previous version, I made another one. It uses an STC8H1K08 microcontroller as the main controller. Different button presses control the motor output, and the LED status is adjusted based on the button press. It shuts down to save energy if there is no operation for 5 minutes. Button 3 controls the power on/off. The original program was a bit more complex; I wanted to use button 3 for speed adjustment, but the program kept having problems. Those who know how can write it themselves. Two front lights are provided, which require soldering with jumper wires. Not soldering won't affect the design. The casing also has some issues, so I won't upload them for now.

Just use the default settings after programming.
