on video How to make Universal Led Tester

 Have you worked with LED based project?

Yes of course we are all working with LED based projects, we need LEDs its an essential part of our project like LED cube, LED chaser Lights etc.... are some of the examples.

The reason i came up with this idea is yesterday i was just working with a LED based project for my college after completing the project i realized that some of the LEDs that iam using is already dead. My whole project gone to waste bin.

So, i come up with this idea to test my LEDs if it is working or not. This LED tester is simple to make, may take 5 minutes or less and its super cheap.

So, lets do this guys.

Firstly we need to collect all the parts that we needed to do this project.

You don't need much parts to do this project. Its small and cheap components, even it may already be in your hand if you are a maker.

Here Is The Parts You Need To Collect:

9volt battery

9volt battery connector

1k Resistor

General purpose PCB(a small piece needed)

Female Heads(two ports)

Hookup wires

Other Tools Used In This Project:

Soldering iron.

Soldering Wire.

Hot Glue / Instant Adhesive Glue.

I think that's all we needed.

After collecting all the parts lets jump to the next step.

In this step we need to solder all the components on the PCB and connect each other. Take a look at the schematics shown i above images and solder the components correctly.

After soldering all the components each other lets go to the next step.

Now in this step we just need to glue the battery connector to the other side of the PCB. Use a hot glue gun or instant adhesive glue.

Take a look at the above images and glue it perfectly.

Here I used an instant adhesive glue in this project.
