Once you have either wired the 4 relays or imported the module, here is a simple Arduino sketch to test the simulation.
: Instead of wiring four separate relay circuits, you can use a single block with clear pins for VCC, GND, and four input signals (IN1–IN4). Where to Download the Latest Library 4 channel relay module library for proteus new
For simplicity in Proteus, you can use the built-in RELAY model and replicate it internally. Once you have either wired the 4 relays
High-quality 2D and 3D models make the schematic more readable. 4 channel relay module library for proteus new
