Today we will focus on the humble RGB LED strip. They cost just $23 for five meters of RGB LEDs (or less than $10 if you want to wait a bit for them to arrive straight from China). Both of these links come with a power supply and a remote control.
The strips are low power, easy to shorten and easy to attach with the sticky back. Many of these ideas are «plug and play», while some need a little more work and create a microcontroller (like the Arduino).

Custom Ambient Lighting
LEDs make great alternative lighting, and with a little work you can make it look stylish too. YouTuber Great Scott! Created this detailed guide to creating backlight wall panels.
In the same vein, YouTuber DIY Perks offers a tutorial video on how to make wall lights.
Both of these projects use warm white LEDs, RGB LEDs can be used instead to add a splash of color.
YouTuber techydiy created an illusion mirror using LED strips. His video shows how to build an elegant wooden case along with LED wiring.
Another great place for LEDs is in the kitchen. This video from the DIGS channel shows more practical aspects of installing them and how good they look!
You can use LED lights to grow plants indoors. In this video, YouTuber RepensTheTurtle walks you through a simple build design.
Make It Smart
In this video, YouTuber Gadget Addict explains how to control an LED strip with an Arduino.
It’s worth noting that you should use logic level MOSFETs like the IRL540N with microcontrollers.
The night part of the above project has another application. Jazzcat123 used a similar scheme to add motion-controlled LEDs to their pantry.
