Here is a second Arduino sketch that will display the mouse X/Y values sent from Processing on a LCD. The system variable pmouseX always contains the horizontal position of the mouse in the frame previous to the current frame. Port.write(str(mouseX)+' '+str(mouseY) + "\n") Void draw() comment: Finish your data, that you send with \n (newline). Use the Processing forums for help with unrelated Processing projects (or hire me for. The most simple one you havebeen using this whole time is the mouse. Calculating if the mouse is inside a square is a bit more tricky.
However, with 0.4.18 and 0.4.19, when the mouse stops moving pmouseX/Y does not equal the current mouseX/Y values.
#Processsing pmouse and mousex update#
We arenow going to focus on inputs for Processing. When developing using the editor, pmouseX/Y seems to update with the new frame so if the mouse stops moving pmouseX/Y will equal mouseX/Y on the next frame. Port = new Serial(this, Serial.list(), 9600) Processing the Mouse We are now on our way to really breaking through in Processing. Simply add a spotlight effect, or mouse-click effect, keystrokes feedback, and even draw on your screen during your presentation, screencast, etc. If you have a I2C LCD available, you could connect it to the Arduino and print out the incoming data.Īs chrisl mentions in the comments, there is still much work to be done to get the raw data in the format you require. In Learning Processing chapter 3, exercise 3.6, Daniel Shiffman uses the mouseX, mouseY and pmouseX, pmouseY variables to draw a line. PMouse overview PMouse highlights important focus areas for your audience. You should see the LED on the Arduino flash on then off quickly as the data is received. I'm using frameRate(1) in the Processing sketch to send the data once per second, so the mouse X/Y values in the Processing window will be slow to update.

Since you can't use the serial monitor to "see" the incoming data from Processing, here are 2 test sketches that may help you determine if data is received on the Arduino.
