Building a simple LED light circuit is an easy and fun electronics project for beginners to get started with. In this article, I will provide a step-by-step guide on how to build a basic LED light circuit using common components that are easy to find.

This project is a great way to learn about basic electronic circuits and components. It also serves as a foundation for more advanced circuit building projects. I will cover everything you need to know, from parts required to wiring up the circuit.

So if you are new to electronics and looking for an easy DIY circuit project, then read on!

Parts Needed

To build the LED light circuit, you will need the following common electronic components:


LED stands for Light Emitting Diode. It is a special purpose diode that converts electrical energy into light energy.


A resistor restricts the amount of current flow in a circuit.


The battery provides the electrical power to light up the LED.


Wires are needed to connect the components together.


A breadboard allows you to prototype circuits easily without soldering.

Switch (Optional)

A switch allows you to easily turn the LED on and off.

Circuit Diagram

Here is a circuit diagram showing how to connect the components:

Let's go through what each component does in the circuit:

Now let's look at how to actually build this circuit on a breadboard.

Breadboard Wiring

Follow these steps to construct the LED light circuit on a solderless breadboard:

1. Insert the 9V battery connector

Connect the 9V battery snap connector onto the breadboard rails marked '+' and '-' for power.

2. Add the switch (optional)

If using a switch, insert it across the positive or negative rail like shown.

3. Insert and connect the LEDs

Place the LED legs into separate rows on the breadboard. The longer positive leg (anode) goes into a row connected to power, while the shorter negative leg (cathode) goes into a separate row.

4. Add the resistors

Insert a resistor into the board and use jumper wires to connect one end to the negative leg of each LED.

5. Connect loose ends

Use jumper wires to connect the loose resistor legs to ground. Also connect any positive LED legs directly to the positive rail if needed.

6. Check your connections

Verify the LED polarity, resistor values and that all components are securely inserted into the correct rows.

7. Power up and test

Connect the battery and flip the switch to complete the circuit. The LEDs should light up! If not, check all connections again.

Tips and Considerations

Here are some important tips when building your LED light circuit:

Modification and Customization Ideas

Once you have built the basic circuit, here are some ideas for modifying or expanding the LED light:


Building an LED light circuit is a simple and fun beginner DIY electronics project. With just a few standard components like LEDs, resistors, and a battery, you can create your own portable handmade light.

The wiring is straightforward and easy to prototype on a solderless breadboard. Once you have the basic circuit figured out, there are many possibilities for creating customized LED lights. The skills you learn making this starter project will be helpful for more complex circuits down the line.

So get a few basic parts together and light up your creativity by building your own LED light circuit. Keep tinkering, modifying and expanding the circuit as you learn more about electronics. Have fun DIYing!
