Beware flashing images in the video below:The Idea
I’ve been using the site Hackster for just over 2 years now, my first project uploaded to there was my Windows 98 Wrist Watch, I’ve also had some help from Elegoo recently with my Scorpion Robot Project.
I asked Elegoo for the above LED kit to make something with and review and I thought I could make a Hackster Badge with their logo on, as a thank you to them for spreading word about my projects as well as give Elegoo more attention to their awesome products!
- Make a wearable with the Hackster logo.
- Make it flash cool patterns.
The first part was to order the LED’s into the Hackster logo:
Next up was wiring up all the positive LED pins to the holes where the digital pins of the Arduino would be as well as wiring ground, I wired the LED's to the digital pins
(except I did not use resistors):
Then I soldered in the Arduino, I had to use wires to get it connected to the board as the Arduino would not fit with pins over the wires:
Finally I hot glued on the battery holder and put a lot of hot glue over the wires to secure them:
And the final look of the front:
And finally adding on a pin to the back to make it a badge:Code
Once the badge was build and the soldering all finally done, I created code that would do a flashy animation to light up the logo and hold it for a while before repeating the animation.
As I hadn’t kept track of what LED’s were going to what pins I had to manually find the pins to LED’s and note them down:
Once I’d figured out the order to light the LED’s in the way I wanted I made the code which you can grab from my GitHub.Flashy

Looks really good and super bright! I highly recommend the resistor kit from Elegoo – with 600 LED’s in the box it will be a while before I have to purchase any more.
In the video I say I’m not sure how long the batteries will last – I noticed on editing at some points the badge appears to be breaking the pattern, I think this is where the batteries are going and restarting the board.Conclusion
The main takeaway from this for me is that I should plan wiring a bit better as well as note what pins go to what LED – for future projects this would make it easier for knowing what pins will light up from what digital output.
But the end result is a cool looking and bright wearable!
Let me know what you thought and see you next time.
