Hi Friends .

How are you?

I hope you are fine!

Today in this instructable we are going to make a simple but very useful Diy project a SIMPLE LED TESTER.

Have you working with LED based project?

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

The reason i come 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 work or not . this LED tester is simple to make, may take 5 minutes or less and its super cheap.

So, lets do this guys.

Step 1: COLLECT THE PARTS

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

You doesn't need much parts to do this project . Its small and cheap components, even may it is already have 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 Headers(two ports)
  • Hookup wires

Other Tools Used In This Project :

  • Soldering iron.
  • Soldering Wire.
  • Hot Glue / Instant Adhesive Glue.

I thinks that's all we needed.

After collecting all the parts lets jump to next step.

Step 2: SOLDERING THE COMPONENT

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

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

Step 3: GLUE THE BATTERY CONNECTOR

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

Take a look the above images and glue it perfectly.

Here i used a instant adhessive glue in this project.

Step 4: Done

Well that's all , we done. Now just take your LED and plug it in your DIY LED TESTER to check the led working or not.

Thanks guys !
