Just fyi, the I version does contain a range of interfaces, also an RC interface.

Grumy_mike, connecting the ground of the arduino with the black wire did the trick. Thx.

The code posted is not pwm, but servo, so I use the white wire.

zoomkat: only one of my 2  12V actuators do still work, so yes I probably fried something smiley-sad.

Sigh, was confused, *this* is the right datasheet.

I have the 'I' option on page 3.

I don't understand - the arduino provides the PWM signal on pin 11, the actuator has a PWM interface. The same interface is used on the 6V which works.

Could I control it with the arduino motor shield r3? (I have one). Thx

This is the spec of the actuator:

Here's a picture,

the actuator is firgelli L12-100-100-12-I

Red & Black of actuator goes to 12V
white wire goes to PWM on arduino
Arduino is on 12V, or as in the picture, USB.

I tried to connect the ground of the actuator with the ground of the arduino, no luck.

Hi, I have problems using a 12 V Firgelli actuator. I just started to use arduino.

Code should be fine, it works with the 6V actuator, so I think it's a wiring problem (however the same wiring for 6V works ok)

I drive the actuator (red, ground) from a 12V.
I connect the white wire from the actuator to arduino pin 11.
The arduino board is powered from the same 12V.

This setup works on the 6V actuator, not 12V. Is this somewhere a voltage problem?

Many thanks !

The code:
#include <Servo.h>

Servo s;

void setup() {
  s.attach(11);
}

void loop() {
  s.writeMicroseconds(2000);
  delay(4000);
  s.writeMicroseconds(1000);
  delay(4000); 
}
