We are going to use a very cheap and useful esp8266-based board. I would recommend buying LOLIN/WeMos boards as they're pretty cheap, reliable and easy to buy.
These boards are compatible with Arduino, which makes them really use to work with, and perfect for our workshop.

We need to install USB drivers for the CH34X chipset so we can connect to our board and flash (install) our programs
Reboot your computer after installing the drivers
We're going to connect your RGB LED using to female-to-male jumper cables.
Make sure your board is not connected to USB before doing this
First, let's connect the jumper cables to our RGB LED.
There's two main controllers for these RGB leds, APA106 and WS2812, and both use the same configuration
If you're using an AdaFruit NeoPixel and you have difficulty locating the flat side, it's the one with the two longer pins
When you're done, it should look like this
Now, let's connect the RGB LED to the board using the male end of the jumper cables, making sure you respect the pins
RGB LED ground to board's GND
RGB LED +5v to board's 5v pin
RGB LED Data in to boards' data pin (D4 in our example)
When you're done, it'll look something like this,
