To automate the simulation, write a simple sketch in the Arduino IDE to sequence the activation of the four relays.

No need to calculate resistor values or coil voltages—it works right out of the box at 5V logic. How to Download and Install the Library

Wire the input pins () to digital output pins on the Arduino (e.g., Pins 2, 3, 4, and 5) or link them to individual Logic State toggles for quick testing. Step 3: Wiring the Load Side For each of the four relay channels: --- 4 Channel Relay Module Library For Proteus

The symbol that appeared on his workspace was beautiful in its simplicity. It was a tidy blue rectangle with four distinct input pins on the left (IN1 through IN4) and power rails (VCC and GND). On the right were the screw terminal outputs: Common (COM), Normally Open (NO), and Normally Closed (NC) for all four channels.

It consolidates dozens of individual pins into a compact block with neat terminal connections. Step 3: Wiring the Load Side For each

To tie everything together, let's look at a practical project: . In this project, the system is designed to safely control four external 12V devices using a ULN2003 driver IC to protect the Arduino. The user sends simple two-digit serial commands: the first digit selects the relay (0–3), and the second digit sets the state (1=ON, 0=OFF). This workflow—from the serial terminal to the Arduino, to the driver, to the relay, and finally to the load—perfectly mirrors a real-world industrial relay control system and is accurately reproduced in Proteus. This simulation setup is a fantastic blueprint for many automation projects, from controlling a home lighting system to managing a laboratory experiment.

Allows controlling up to four loads independently.

Compile the following code in the Arduino IDE and export the compiled binary ( .hex file): On the right were the screw terminal outputs:

Phototransistors that protect the microcontroller from high-voltage spikes.

Most libraries include LEDs that light up when a relay is triggered. How to Install the Library in Proteus To add the library, follow these steps:
