Hello, I hope everyone is ok,
Could someone help me to convert a barcode to a pdf file, I've tried in various ways with no success, this is what I got so far
Searching the forum is always a good start...
Thank you very much!!
Sorry for bothering you, how can i make the flow to generate random qr values?
random what - numbers? strings? of a particular min/max/length?
PS, the answer is yes.
Thank you, I already did it, sorry for so many questions, but, I'm new to Node-red, this is my las question 
, I'm trying to get the data that you put in the csv node from the dashboard, but I haven't been able to do it, could you please help me?, this is what I got so far.
