HELLO everybody
I have a problem with my arduino cart , I can't make a communication between ardduino cart and Processing programme,all thing is very good, the arduino and the code but I can t make the communication betwenn their, please I need help

 

What is an Arduino "cart"?

And where is the "processing program" running?

And how are they connected? That is, how do you expect or need them to communicate? What is being sent between them?

I am making an educated guess that English is not your birth language. Please help us help you by providing more information. Sketches, schematics, purpose, etc...

 

Hello exactely english is not my birth language, I trying to improve it, so I use the Arduino Uno R3 and sorry for the word "cart",
I am trying to draw a curve in processing when I change the value of potentiometer attached in the arduino,
All codes are running well (arduino, and processing), the results on the processing is only a dark window, and when i went print the values of
potentiometer I don't have any results, Thanks and sorry for my bad english.

 

Have you done proper configurations?

 

Hello , I am trying to resolve my problem and I deduce that does not work only when I use the Arduino Firmata labrery ,

 

I resolved the problem of comunication it was a problem of the speed of deferent codes , i fixed it to 9600 in the processing code and the arduino code

 

Good!
