Hi friends this is Syed and this is my first post I have opened my hackster.io website account is on 8th may 2015 from then I am the repentant of the website today i thought to start contributing to hackster.io :)
I am writing this instructable because I have got issue how to test a LED when we are building led cube ,where we have to test the leds before fixing in the cube, we have every time we have to fix a resistor to LED and connect it to 9V battery or LED+Resistor to a five volts power source i.e; adaptor or 7805 regulator power
Step 1: Collecting Raw Materials- Perf-Board - 1No (required size )
- 3.3V battery holder -1No
- Hookup wires Red and green(P.S: that's your wish to remember polarities here I have used red for + and green for - )
- Berg Strip Female 5pins -2No (that's your wish to test no of LED's but the intensity goes down if you add more)
- 3.3V battery -1No
- LED's for testing
We need a good soldering iron i use
- Solder on 25W soldering iron
- Soldering Led wire
- Flux paste
- Soldering stand
- Desoldering wik
As per the frizing schematic we do the soldering and the output can be seen in next step.
Step 3: After SolderingWe can see the after soldering our project is ready to jump out testing 100's of LED's.
PS: where MH stands for Maker's Hive (https://www.facebook.com/makershive/ ) where this project build.
In next step we can see how the LED testing can be done.
Step 4: Testing of Easy LED TesterWe can see now the Easy LED Tester is ready.
We can test the LED's.
It's very easy if the leads of led are short then it's easy to know it's working or not.
It's very useful when you are dealing with large quantity of LED's (i.e; building cubes and LED Matrix).
