Cats just want to straight up do a murder on that little red laser dot. Hunting is great exercise for cats, and it's always amusing to watch them go on the attack! Sure you can just grab your laser pointer and go for it, but you always know where the laser is going to be. Let's inject a little chaos into the mix with a pan/tilt turret to make a laser that moves to random positions at random intervals!

Step 1: Project Parts List

This should work with any hobby servo driven pan/tilt turret. Here are two suggestions:

RobotGeek Pan and Tilt:
This is a great choice if you'd like to add a camera or attach a fishing pole type cat toy.

1 x RobotGeek Pan and Tilt Kit w/Servos
1 x Laser w/Mounts
1 x Geekduino or other Arduino UNO equivalent
1 x Sensor Shield (recommended for easy wiring)
1 x 7v5a Power supply

Mini Pan-Tilt:

This is a good choice for low cost, but using 9G servos limits the weight of what you can add.

1 x Mini Pan-Tilt Kit
2 x 9G Metal Gear Servo
1 x Laser w/Mounts
1 x Geekduino or other Arduino UNO equivalent
1 x Sensor Shield (recommended for easy wiring)
1 x 6v2a Power supply

Step 2: Assemble Your Turret

If you're using the RobotGeek Pan/Tilt, assembly instruction can be found here.

If you're using the Mini Pan/Tilt, assembly instruction can be found here.

Attach the Laser, and let's wire it up!

Step 3: Wiring

Device	Pin Type	Pin #
Pan Servo	Digital	10
Tilt Servo	Digital	11
Laser	Digital	2

Make sure to set the voltage to VIN for larger servos running 7v. You can keep it on 5V for 9G servos or run it VIN with a 6v power supply. Super simple wiring. On to the code!
