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.
