What is a Microcontroller?
Microcontroller Definition
A microcontroller is an IC that processes commands from a PC via protocols like Serial, Ethernet, and CAN.
Microcontroller Components
Transistor
Diode
Resistors
Relay
LED
Digital Output
The microcontroller’s digital output is a low-amperage signal, suitable for small loads like LEDs.
Transistor Function
The transistor acts as a driver, providing the necessary current to the relay to control the circuit breaker.
Working Principle
The microcontroller sends a command to turn on the transistor, which activates the relay and switches the circuit breaker.

Battery charging process using AC adapter
The process of charging the battery using the AC adapter is as followsConnecting devicePlug the AC adapter into the power outlet, making sure the connection is secure and stable. At this point, the AC adapter starts to obtain AC power from the grid.Connect the output of the AC adapter to the device that needs to be charged, usually through a specific charging interface or data cable.Ac adapter operationInput AC conversionThe circuit inside the AC adapter first rectifies the input AC power, conve

The circuit working principle of one-way switch
A one-way switch is the most basic type of switch that has only one input (often called the "normally on" or "normally closed" state) and one output. The working principle of the one-way switch is relatively simple, but it has a wide range of applications in various electrical and electronic devices. The following details the circuit working principle of the one-way switch:The basic structure of a one-way switchA one-way switch usually consists of the following parts: Contact: A metal part used

What is the effect of applying alternating current to a DC machine?
Applying alternating current to a DC motor can have a variety of adverse effects because DC motors are designed and operate to handle direct current. The following are the possible effects of applying AC to a DC motor:Cannot start and run properly No natural zero crossing: AC has no natural zero crossing to help the motor start, while DC motors rely on constant direct current to establish a magnetic field and start. Inversion phenomenon: The sinusoidal waveform of alternating current changes dir
