Hello friends, I hope you all are doing great. Today, I am going to share the new Relay Module Library for Proteus V1.0 . The blue 5 V relay module is in almost every Arduino kit: one, two, four or eight SONGLE relays on a board, with optocouplers, LEDs and screw terminals. It lets a small Arduino pin switch a lamp, a fan, a pump, a solenoid lock or a motor, with the load completely separated from the Arduino. Home automation, plant watering, garage doors and smart sockets all start with this module. Now you can build and test them in Proteus. Behind the parts sits our own model , not a symbol on top of a Proteus relay. Each input works like the real one, active LOW through an LED and a PC817 optocoupler. Each relay has a coil that takes time to build up its current, an armature that picks ...
