Sure. It's easy to start writing flows similar to BLINK and turn an LED on from an input. But once I get past that point it's like drinking from a fire hose.
I've been trying to figure out how to do a simple task like multiply two numbers together. I have a data stream coming in through a Serial port that is working and using a CALCULATOR node I can divide that by a constant. But I need to multiply it by a number from an INJECT node. I haven't found any tutorial that tells me how to do that that doesn't assume I'm an expert in NODE RED and JAVA.
Can anyone point me in the right direction? It's obvious I'm missing something very fundamental here. This should be easy.
