Installing libraries is a basic Arduino skill. Please click the link to Erin St Blaine's tutorial as it includes instructions. Again, this is the sort of thing you need to search out for yourself as it's not specifically related to my project.

Yeah I tried to reply but I couldn't either yesterday...I really don't recommend using the 12V strips for portable use. they're more intended for use in cars where you have a stable 12V supply. You don't wanna be carrying around a 12V battery. Also you'd need to level shift the signal from the microcontroller to 12V.If you only want an outer heart, my code will still work. There is an option to change the total number of LEDs and the number of LEDs in the outer/inner heart.Maybe look at these LEDs:https://www.aliexpress.com/item/2X-50pcs-string-WS2812B-5050-RGB-Addressable-LED-Module-Black-Crystal-Wire-Red-Green-White-Wire/32572189235.htmlhttps://www.adafruit.com/product/3630https://www.adafruit.com/product/3631

Hi there! I'll try to help you as best as I can.You don't need a laser cutter. You can cut the heart shape out of cardboard with a knife if you'd like to use that shape. You can do heatshrink either with a lighter or with the upper part of your soldering iron (not the tip). You can also get a cheap heat gun for about $10-$15.I don't know that much about MakeCode so I can't help you programming that. However, one of the effects I include in my code is basically that pulsing light in a single color, so you'd only have to edit the color used by that effect.I do not recommend 12V LEDs for this project if you want to use it with a microcontroller. You need a MOSFET for each color channel. It's a much more advanced circuit. See here: https://learn.adafruit.com/rgb-led-strips/usage Additional...

See here: https://learn.adafruit.com/rgb-led-strips/usage Additionally, my code would not work with those LEDs.Something that might work for you: there are pre-existing remotes/controllers for 5V and 12V LED strips. No programming is required. Just search for "5V LED controller" and "12V LED controller" on Amazon or AliExpress. This one looks like it might do what you want. https://www.aliexpress.com/item/DC12V-24Key-Mini-RGB-Controller-IR-Remote-Controller-With-Mini-Dimmer-for-5050-3528-Led-Strip/32701289051.html?ws_ab_test=searchweb0_0,searchweb201602_3_10152_10151_10065_10130_10068_10344_10324_10547_10342_10325_10546_10343_10340_10548_10341_10545_10084_10083_10307_10059_10314_10534_100031_10604_10103_10142,searchweb201603_36,ppcSwitch_4&algo_expid=2ae5b7c3-2fac-45df-8bd9-76a5e244edbf-7&algo_pvid=2ae5b7c3-2fac-45df-8bd9-76a5e244edbf&priceBeautifyAB=0

Victor and Yuuri from Yuri on Ice! :)

Thanks! I'd like to get into 3D printing more doll-sized furniture as well.

Well, it doesn't have to be plastic. If you had sturdy cardboard or foamboard that would work too. You can trace the pattern and cut with a knife.

I only used the Uno for the purpose of testing the LEDs while soldering. The final installation uses a Circuit Playground. A Trinket would not have enough memory for the code I wrote.

Thank you! I love Circuit Playground too. It's so convenient having buttons, LED indicators, sensors, etc, all together in one board!

Thank you!

This might be a silly question, but where did you get the plywood? I went to Home Depot but they didn't have any 1/8" plywood.

Good idea! I think 1/8" thick wood might be a bit thick for a bookmark, but 1/16" wood is available.

You may be able to rig something up with command hook type products. I have used their medium cord clips to hold LED strips.

Oooh, nice work on those! :)

Thank you so much! Neopixels are so much fun. ?
