Hi, I am completely new to Node-RED but I love it already.
I have an arduino board connected to my raspberry pi, I need to send a one character output from the pi to the Arduino based on another input that comes from a tape dispenser.
Input ----------------- Raspberry Pi --------[read] --- if [variable}-----payload ------ Arduino.
Now I have different inputs coming from my tape dispenser and they are all in the form of @number. I want to trigger a different payload for each possible input.
The total of inputs are 13
The outputs for the arduino are a 1 character payload [1/2/3/4/5/6/7/8/9/a/b/c/s]
I don't know if a single function can handle it or if I need different functions.
