Once you have either wired the 4 relays or imported the module, here is a simple Arduino sketch to test the simulation.

Each of the four channels can be controlled individually via input pins (IN1 to IN4). Visual Feedback:

Matches the VCC, GND, and IN1-IN4 pinout of real hardware.

📍 Relays bridge the gap between low-voltage logic and high-voltage power.📍 Prototyping: Simulation reduces the risk of "blowing" a microcontroller during testing.📍 Efficiency: A 4-channel module simplifies wiring compared to four discrete relays. If you'd like to move forward, let me know: Which microcontroller (Arduino, PIC, ESP32) are you using? Do you need help with the schematic wiring or the C++ code ?

The simulation model uses the exact pin configuration found on commercial modules: 5V Power Supply. GND: Ground Reference. IN1, IN2, IN3, IN4: Microcontroller input control pins.

To add the new 4-channel relay module to your component list, follow this manual installation workflow:

Wire the terminal of each relay to one terminal of an individual AC Lamp. If you'd like to move forward, let me
