i interfaced arduino with raspberry pi and getting serial data on node red from serial node but i want to print sensor data on dashboard gauge
My msg.payload is giving "distance:xx"
i am using ultrasonic sensor to get distance i already done it with pisrf node
@mani2411 Right now your post isn't a question, its just a statement. It really helps if you spell out what you want clearly and also explain which bit you don't know how to do.
What have you tried?
msg.payload set to something like
distance:xx - I assume you want to pull the
xx value out of the payload to pass to a dashboard gauge. Is that right?
thanks for being so patient i got it working can i use any other language instead of js for function node
