WLED ON XIAO ESP32

Hi, all

If you're not familiar with WLED, the WLED Project is a web server that controls LEDs and SPI-based chipsets. It can control two types of LED strips: digital addressable and analog non-addressable. WLED also provides open protocols to communicate with platforms like Amazon Alexa, Google Assistant, and Phillips Hue, it is based on both ESP controllers, and it is completely open-source. so let's look at how to install it in our tiny Xiao-ESP32-S3 from Seeed Studio i also bulled a encloser for it

Supplies

1. XIAO-ESP32-C3
2. WS2812B led strips
3. Ribbon cable
4. 5v power supply

Step 1: Case for XIAO in Fusion 360

First of all, let's talk about how I made a case for Xiao in Fusion 360.

1. Imported a 3d model of Xiao from Grabcad 
2. Sketched a square 
3. Extruded it to the required height 
4. Done Fillet on the 4 corners 
5. Used shell tool to convert it into a 1 mm thick wall 
6. Removed two sides one for the USB-C port and another for cables and antenna 
7. Made a cap of 1mm by utilizing the projection tool 
8. Extrude another 1mm from the cap and push the walls for the snap-fit of the cap 
9. Made an airway for Xiao on the cap by cutting with a sketch 

Done !!

Step 2: 3d Printing

Used by Anycubic Kobra 2 neo for this with a Black PLA

Step 3: Flashing WLED to Xiao

Now let's flash the WLED to xiao esp32c3, connect the Xiao with USB 

XIAO ESP32C3 is a low-cost, high-performance RISC-V IOT development board that supports Bluetooth and WiFi and low-power mode.
