Hey everybody. I am new to arduino and I have some questions regarding a project im doing from the arduino playground. I followed the instructions on the playground link Arduino Playground - SingleServoExample
My question is about a warning I got in processing. I opened procesing and pasted the code it told me to use in processing. It worked just fine. The servo moved along with my mouse. But at the bottom of the processing screen I got this warning even though it worked. Why do I have this warning? Also when I move the mouse right the servo goes left and when I move the mouse left the servo goes right? How can I reverse this?
