I am new to using arduino's, servos and the like. I need to use an arduino uno to control 3 actuators for a final year project. My team has already purchased 1 linear servo from servo city http://www.servocity.com/html/heavy_duty_linear_servo__115__.html . I have tried to find code to help me control the actuator but with no luck. I have hooked up the digital output pin 3 to the yellow controller wire and am using this http://principialabs.com/arduino-serial-servo-control/ tutorial and code to try and make it work. I did set the maxpulse = 2000 and minpulse =1000 according to the specs from the servocity site. I also give it a slower turning (retracting, extending) rate. The only thing that happens when i upload the code is that i hear the actuator make noise (it was at the max stroke when i started with it). I have checked the power supply voltage and to make sure it is the correct 12v and the current should be enough since i'm using a 360 watt switching power supply.
If someone could let me know what i'm doing wrong that would be great.
sorry if this is in the wrong section.
