<html><body>Control WS2812B LEDs easily via a powerful RESTful server running on Arduino. Unleash creativity by executing complex programs with a simple file upload in Light Definition Language (LDL). This project differs from other LED controllers: end users need minimal technical knowledge and user-friendly tools can generate the LDL that can be sent to the server. Example: switch between red/blue every 1 second forever: <figure><img src="https://projects.arduinocontent.cc/abb16656-20c8-4f04-8c77-7aa464820980.png"/><figcaption></figcaption></figure>Example: a more complex Christmas lights program <pre>{ </pre><pre>	 "name": "Bottle Program", </pre><pre>	 "instructions": [ </pre><pre>	 { </pre><pre>	 "repeat": { </pre><pre>	 "times": 0, </pre><pre>	 "instructions": [ </pre><pre>	 { </pre><pre>	 "repeat": { </pre><pre>	 "times": 10, </pre><pre>	 "instructions": [ </pre><pre>	 "0505000003FF00000099003333FF" </pre><pre>	 ] </pre><pre>	 } </pre><pre>	 }, </pre><pre>	 "0401000005000000000FF00", </pre><pre>	 "0401000005133FF33000000", </pre><pre>	 "04010000050000000FF0000", </pre><pre>	 "04010000051FF0000000000", </pre><pre>	 "040100000500000003333FF", </pre><pre>	 "040100000513333FF000000", </pre><pre>	 "030100000101919FF000000FF00", </pre><pre>	 "030100000111919FF000000FF00", </pre><pre>	 "070100000A3C104FF00000099003333FFFFFF00" </pre><pre>	 ] </pre><pre>	 } </pre><pre>	 } </pre><pre>	 ] </pre><pre>} </pre><h3>Project goal</h3>Empower creativity and bring lighting designs to life with a user-friendly LED driver!
