3v LED Dimmer Circuit

How the 3V LED Dimmer Circuit works?

The Circuit works with the basic precept of a Transistor. The Potentiometer creates a Voltage divider inside the circuit. And whilst we rotate the Potentiometer then It creates Different voltage Levels for the LED Dimmer. These Voltage stages are sent to the Transistor’s Base with a 10k Current Limiting resistor. This resistor is important. Otherwise, the Transistor could be damaged. Now the base voltage changes. For this, the Transistor flows modern from Collector to Emitter. And The Loads that are connected with the transistor could be Powered Up. In this way, the 3v LED Circuit works.

First, you will want an NPN Transistor. Here I am the usage of BC548 Transistor. You can also use every other NPN Transistor as well. I bent the three Legs of the Transistor. Then I even have Pre-tin the wires for higher soldering. In the picture, you can see the Pin output.

Now you will need a 100k Potentiometer. Connect the Transistor’s Emitter Pin with the Potentiometer nook Pin.

Connect LED with the circuit. Connect LED +ve with Potentiometer. And join LED -ve with the collector of the Transistor.

Here are the connection points of the circuit. The voltage might be according to the load. Here I will connect 3v LED so I decided to hook up with 3.7v 18650 Battery. if you have 12v masses then you can connect 12v as well.

So, Lets Test the LED Dimmer Circuit.
