LED Flasher Circuit with Relay

Introduction:

Today during this text we are becoming to form a LED Flasher circuit with a Relay. this is often a simple circuit based upon a Multi-Color LED and a General NPN Transistor. So, Let’s make this easy circuit.

Schematics of the LED Flasher Circuit with Relay:

How does the circuit work?

Here we are giving 3v to 5v to the circuit. The Multi-Color LED is connected with the rock bottom of the Transistor. The LED changes its color. So, for this reason, the Transistor triggers and thus the relay turns On/ Off while changing the color. For this triggering, the Relay also triggers.

As a result, the load which is connected with the Relay also triggered. For the Load, I even have used 2 LEDs. one of the LED is connected with the NO Pin and thus the opposite pin is connected with the NC Pins. Here NO means Normally Opened and thus the NC means Normally Closed Terminals.

Here you'll also connect any load with it. it is a relay so it can handle much higher loads than Transistors. like you'll control 100W Lights easily. So, this is often an easy and Power efficient way of Flashing LED.

Note:

The circuit is based upon Relay. The Relay could also be a robot it works but there is a big noise that comes from it. So, you need to look out for these kinds of things.

Flashing is completed by the Multi-color LED. so if the LED is broken then the circuit won't work. Please don't use a voltage above 5V. otherwise, the Multicolor LED is getting to be damaged and thus the Relay coil could even be heating up quickly.
