Micro SG90 Servo Motor

The standard micro servo of hobby robotics: nine grams, 180 degrees of travel, and controlled by a single PWM pin with the Arduino Servo library. Its plastic gears keep it light and cheap but are the first thing to strip if the arm is forced or the load is too heavy. Perfect for pan-tilt mounts, robot grippers, model control surfaces and small mechanisms. Power several servos from a separate supply, not the Arduino's regulator, or the board will brown out and reset. Controlled by one PWM pin with the Servo library; Very light at 9 grams for mobile and airborne projects; Horns and screws included; The most widely supported servo in tutorials
