Receiving MQTT Messages


#1

Hi everyone,

I am completely new to Noodl and am struggling!

I have an MQTT broker set up and linked to my project, the aim is to change the colour of a rectangle when a message is received. What general flow chart will allow this to happen?

Sorry if this is a bit vague, any help is much appreciated!

Hi,

I’m sure there are better ways to do this, but have you tried a ‘Receive Message’ node with specific payloads?
Since I don’t know what data types you’re passing, this is just an example of r, g, b int’s which get changed to a hex code.
