I want to flash an RGB LED in different colors. Arduino code looks like:

setColor(255, 0, 0); // red  
delay(1000);  
setColor(0, 255, 0); // green  
delay(1000);  
setColor(0, 0, 255); // blue  
delay(1000);

How would i Node this out?

This is explained here: [https://xod.io/docs/guide/simple-traffic-light/](https://xod.io/docs/guide/simple-traffic-light/) using “led” nodes. Your RGB LED will be connected to 3 Arduino pins, so you should be able to use “led” nodes instead of setColor().

Also, you can watch a recent video where @dronebotworkshop does exactly that.
