Download the Sketch
A .zip file with all of the RoboTurret Sketches can be found here.
Unzip the file and you will have a folder called
We recommend that you create a folder
RobotGeek Sketches in your Arduino user folder and put the
desktopRoboTurretV3-master in there. The rest of this guide will assume you've placed your sketches in the following folder.
Arduino -> RobotGeek Sketches -> desktopRoboTurretV3-master
This will be the same 'Arduino' folder you put your libraries and robotgeek tools in, and NOT the folder where the Arduino application is.
Direct Control - Joystick
The easiest way to control the Desktop RoboTurret is with the included Joystick and a Pushbutton. The Joystick consists of 2 self-centering potentiometers that the RoboTurret can use as Analog Inputs. The horizontal axis will control the pan servo while the vertical axis will control the tilt servo. The pushbutton can be used as a Digital Input to toggle the laser on and off.
The Joystick code can be found at:
File -> Sketchbook -> RobotGeek Sketches -> desktopRoboTurretV3-master -> roboTurret3_joystick
Wiring for joystick control is as follows:
|Device||Pin Type||Pin #|
By changing the
speedvariable, you can adjust the overall speed of the turret. A higher value will cause the turret to move faster, while a lower value will cause it to move slower. Values from 5-500 work the best.
If your turret is 'drifting', or moving while you don't want it to, you may need to lower the
DEADBANDLOWor increase the
Alternatively, if your is not responding to small movements on the joystick, you may need to increase the
DEADBANDLOWor decrease the
