Predator cosplay

Hi all.
I'm making a predator suit and I want to make the shoulder Cannon that follows my head's movements. I have managed to use a gyro sensor so control the up and down movement. How do I make the cannon go left and right? What kind of sensor would work for this?

The sensor that tracks your head movements should work for left and right as well as up and down.

To make the cannon point left and right, use a motor or servo.

Are you wearing the helmet with this costume or a rubber mask?

Just a helmet, no mask so far.

I might have done something wrong because I can only get it to move in one axel, if I move the 6050 gyro side to side it does nothing
