Via a code i wrote for the arduino uno and processing i made a program that detects motion via a webcam. in the videoframe there is a crosshair(targetbox) that follows a moving object and sends a signal to arduino so that my pan/tilt servos are causing the paintball gun to aim to the area where the crosshair on my screen is aiming. but the servomovements are so rough that the gun overshoots and makes my whole frame+tripot vibrate. </p><p>&nbsp;</p><p>With steppermotors i would like to make sure that when the onscreen crosshair detects movement, it will go from 0 to 1 without the rough movement.</p><p>&nbsp;</p><p>For exampel. a moving object coming from the right walks into the camera field of vision, and the gun/crosshair is aiming left cause there was nothing moving. With my servo&#39;s it instantly reacts, aims the gun at the target coming from the right and keeps aiming at it, but the servo is moving very spastic, with steppers i would like to have the gun slow down the moment it&#39;s on target and follows it very smoothly as the target moves forward.</p><p>&nbsp;</p><p>So this might be the way to go <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-40af67ff-3068-4306-8d4e-5d89392eb03f/contentimage_5F00_1.png:16:16]</span></p><p>&nbsp;</p><p>Really helpfull video <span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-40af67ff-3068-4306-8d4e-5d89392eb03f/contentimage_5F00_1.png:16:16]</span></p><img src="https://community.element14.com/aggbug?PostID=15524&AppID=145&AppType=Weblog&ContentType=0" width="1" height="1">
