Is it possible to use the motor encoders on the Arbotix to drive a solenoid capable of pulling a gun trigger? I was thinking about connecting the solenoid across the +/- left motor outputs and outputting a 100% duty cycle for a few milliseconds. Then I found a thread about using solenoids with relays http://forums.trossenrobotics.com/archive/index.php/t-1492.html. So instead of the Arbotix driving the solenoid I'd use a circuit like this one suggested by ScuD http://forums.trossenrobotics.com/showthread.php?t=2994 and the Arbotix would only have to switch on the circuit which drives the solenoid. I suppose this would be necessary if the Arbotix wasn't able to drive the solenoid, but are there any other advantages of this additional complexity?

Is there a better way of mechanically pulling a trigger? I think Gepetto used a servo. http://forums.trossenrobotics.com/showthread.php?t=1439

Thanks

Edit: Resolved. Going to use a relay with the Solenoid. Thanks Andrew.
