Jan 09, 2014 Today's Arduino tutorial is a response to several requests asking for how to accomplish multiple argument commands from the PC to the Arduino. Have a comment or suggestion? Contact me via: Email. Feb 26, 2018 NOTE: I will be using a DHT11 temperature sensor to produce data on the Arduino end. Since this is a tutorial on reading data from the serial port using Python, not Arduino, I recommend visiting a DHT11 tutorial to learn how to print temperature data from the sensor to. A simple example of receiving data from the Arduino. Arduino to Visual Basic 2013 Communication. The example uses a very simply form and shows what ever it recieves from the Arduino in a text box. The Arduino Sketch. The Arduino Sketch sends the string “1234” over the serial connection once every second. I'm currently working on an arduino project at University. Basically what I am trying to do is send a string of data from VVVV to arduino, however I need to parse the data into an array and I have absolutely no idea how to do this! Arduino serial data parsing. Ask Question Asked 7 years ago. Active 3 years ago. My problem is that when I want to parse my wheel speed command on my Arduino I must parse from up to 4 separate bytes to int, for example s,-100,-100 makes my robot go backwards at full speed.

I'm currently working on an arduino project at University. Basically what I am trying to do is send a string of data from VVVV to arduino, however I need to parse the data into an array and I have absolutely no idea how to do this!
The string being sent from VVVV is something like this; U,c,R,|,W,H,P and I need each of those values to be written to a specific servo each time, so value 1 need to go to servo 1, and so on.
Here is my code at the moment, I realize its coded pretty badly, and I do intend to make to make it more efficient when I have worked out how to parse the data.
Edit - I should probably mention that I'm eventually looking to use 7 servos, but for the moment I'm just using 4 in my circuit. Also, when I upload this patch and enable VVVV, the arduino just disconnects.

@opc0de This serial issue has cause a lot of confusion. Including to myself. Possibly similar issue here.
I recently dabbled into this. The Arduino automatically resets when it receives serial communication from most things other than the Arduino IDE. This is why you can send from the IDE but not node.js.
I have an Uno and put a capacitor between Reset and Ground.Here's a page with some good info on the subject. Good luck. http://arduino.cc/playground/Main/DisablingAutoResetOnSerialConnection

If you want to assign the value as soon as received, you can do this:
If you want to have the received values stored on the array to do something more later, then:
