When you type a URL into your browser it makes an HTTP GET request to the server where that website lives. HTTP is the client/server protocol that runs a lot of the internet. To talk to the ESP8266 we will be using HTTP (HyperText Transfer Protocol). Output 5V and up to 2.4 Amps to the ESP8266. I do a lot of projects so the 3 pack has been the best value for me. You just need to make sure it is capable of carrying power as well as data. You probably have 38 of these in your junk drawer. Used to connect the ESP8266 to the LED strips. No one does just 1 WLED project and they are really inexpensive.
Honestly, you might as well get the 4 pack. I have been running these cards in all of my Raspberry Pis for a while without issue. It’s a pretty good deal for the price if you don’t have the parts already. This kit comes with the board, power supply and heat sinks. I used a Raspberry Pi 4 4GB to make this tutorial but you can absolutely use another version of the Pi if you have one laying around. Here are all the parts I used to make this work. If not, check out how to get started with WLED and then come back here. You should also have a working installation of WLED already. I wrote this tutorial using a Raspberry Pi running the latest version of Raspbian but it should work on pretty much any host running Linux. This tutorial aims to help those people automate their WLED setups. A lot of people are already using a Raspberry Pi at home for one thing or another. Not everyone has a smarthome running SmartThings or HomeAssistant. I use SmartThings and webCoRE to automate my WLED installs but I totally understand why people are asking for this. So I decided to make a post covering both requests. How can I control WLED with a Raspberry Pi? These are the 2 most common requests/questions I get… I have had many people contact me via Twitter or email me about these posts. Since then, I’ve been making a bunch of WLED tutorials. I have 10+ WLED installs in my house as I write this. I started using WLED last year and quickly switched all of my other LEDs over.
