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.
