Servo Motor Plastic Wheel SG50 Full Set Normal
Price in Sri Lanka

This component is ideally suited to projects requiring controlled rotation. This is the Tower Pro SG50 Micro Servo and armature kit. These motors are compatible with a large range of shields like the common Arduino Motor shield. They are easy to use and can be added just about wherever you can find a 5V source.

This servo is pulse controlled. This means that supplying a pulse will move it to a particular angle. In this case 0° is a 1.5ms pulse, 90° a 2ms pulse and -90° is a 1ms pulse. This may not be set by your controller by default or give you the full range of movement as such you may wish to try up to 2.25ms and as low as 0.75ms. Be aware that if you go to far you can break the servo.
