Interfacing Relay Circuit in Proteus with Arduino Using Push Button Activation
Learn how to simulate a relay circuit interfaced with Arduino in Proteus, where a push button activates switching to safely control a motor powered by a 220V AC source.
What is a Relay Circuit?
A relay circuit uses a relay as an electrically operated switch to control high-power loads through a low-power signal. The setup includes a relay coil powered by 5V from Arduino, a driver transistor/module, freewheeling diode for protection, and contacts connected to the load like a 220V AC motor. When energized, the coil's magnetic field closes contacts to allow current flow; de-energizing returns them via spring action.
This Proteus simulation demonstrates button-activated relay control with Arduino Uno. The push button sends a low-voltage signal to toggle the relay, switching the motor while an LED provides visual status indication
