KOOKYE Lilypad LEDs Red/Yellow/White/Blue/Green (25x Lilypad LED) Wearable E-Textile Sewable Electronicsfor Arduino Rapsberry Pi Microcontroller Board

These are a good bargain LED to use with conductive thread like that in LilyPad kits. These are not as good as the Lilypad LEDs, but they work well enough. I tend to use a couple extra loops of thread through the holes on these LEDs before continuing the circuit stitching to ensure a good connection to the conductive area and not have any problem lights. I also test each light before using it in a project to avoid headaches.

Having these extra colors (and I also ordered extra thread) means I can go further on one costume or make one color lighting string on the costume. Its really cool seeing something I made light up!

All working out of the box. Nice set of lilypad leds. Voltage is 3 volts. Decent soldering on all of them.

These will come attached but are very easy to break apart. Nice small design with good size pads for easy soldering. These have a built in 150 Ohm resistor (R) so they can be connected directly to a voltage supply.

These LEDs work well with any electric circuit. We have used them successfully with both our Arduino uno and our lillypad sewable circuits kit. The lights are bright, the colors are pretty intense. The blue and yellow are less intense than the red orange and green. There are 5 each of 5 different colors. They are easy to use individually. A great addition to our STEM station in the garage. I cant wait to see what ideas my kids come up with for these.

Im working on a couple of different Lilypad LED projects - a hat and a vest. These are priced right, bright and easy to use. For clothing, conductive thread is the best bet. Im used to the more traditional old-school - use thin wire, solder it to the LEDs and sew the wires in a few spots to keep it in place and pull them through hems and along seams. Conductive thread makes this so much easier. These light up between 2.5 and 5.5 volts (5.5 is the max for Lilypad .) That means that you can power these manually via a USB battery pack.

I’ve used these for science activities in my classroom. They work perfectly in paper circuits and etextile projects.

These worked (I used them for a STEAM class for elementary school) although I’ll note that some of the colors are more vibrant than others.

I own and operate a few 3D printers as a hobby and one of my pastimes is designing, printing, and assembling 3D printed LED lights. Ive been wanting to try some SMD LEDs on a light but cant bring myself to butcher up one of the many LED strips I have lying around.
