code is executed on your computer. On the Arduino, you need to upload
StandarFirmata as explained on their github page.
The code from the Arduino <--> RFID tutorial you gave us if for
Arduino only. If you want to use it with johnny five, you need to implement
the code by your self or look for someone who did that for you on github.
If you're having this problem, chances are someone else also had it and
might have found an answer.
node serialport, you'll be able to read the
Serial.print() outputs of the Arduino. You can output
Hope it helps !
If you need more help, feel free to ask! :)
So if I understand it correctly: you have the RFID reader connected to
the Arduino. The Arduino is connected to a computer. You want to read the
RFID and send the information to the computer. The computer must be running
a server and must be able to get the data from the USB port. All people
connected to the server from the iPad should see the information in
realtime. Is that correct?
If so, you need a node server,
node-serialport to get the
data from the USB and a web app such as express.js to show the data to your
clients. The best way to do that would be to format your data as json so
that it could be easily parsable on the server.
Okay! So here you can find two great tutorials by Tom Igoe on how to use
Arduino and Node.js.
- Arduino Serial to Browser: Here you'll learn the basics
node-serialportand how to use it with your Arduino.
- Serial to Browser using node.js : Here you'll learn how
JSONize your Arduino data so that they can be easily
accessible through your
web app and
uses an accelerometer for his data, but I guess you can directly use your
I'm sure that you'll have many more questions after this but it will be
a good start!
Hope it helps! :)
