[SOLVED] Problems sending data from Processing to Arduino through serial port

[glv]

Try the “fix” to SimpleWrite:

Processing to Arduino Serial Library Example

I modified the existing “SimpleWrite” example to: save and check for the state of mouseOverRect() print state to console only writes serial data once a delay() to wait for Arduino to reset once connected to it; in my case, it is an Arduino Mega 2560 R3. I kept the spirit of the original example intact and left it as a “Simple Write” program. My edit of “SimpleWrite” example so it only sends data once: /** * Simple Write. * * Check if the mouse is over a rectangle and writes the status …

I corrected the link in previous post.

The Arduino code for it is in the examples in the Processing IDE and here:

After all that is said and done you need to get a simple working example going and then start layering more complex code.
