Simple timer circuit in Proteus
In this video, you can see a simple timer circuit simulator with capacitor and resistor.
With this circuit, after pressing the relay key, it will be active for 40 seconds and then the relay will be cut off.
To change the time the relay is active, increase or decrease the value of the capacitor.
If you have any questions, comment below the video so that I can answer it.
