Adafruit Mini Pan-Tilt Kit - Assembled with Micro Servos
This fully-assembled pan-tilt kit is the perfect way to give your project full range motion with two micro servos.
Can rotate 180° from side-to-side
Can tilt up & down 150°
Comes fully assembled with two Micro Servos included and a 38mm x 36mm space to mount a camera or sensor or whatever you like
Since the motors are plain, every-day analog servos, you can use any microcontroller or driver
The pan-tilt is an easy way to give whatever you're making both left-right and up-down motion. In Adafruits' demo, they hooked this up with a Trinket Pro and made it do a little dance with the Arduino Servo library
