FEETECH FS90R 360 Degree Continuous Rotation Micro Servo Motor 9g for RC Helicopter Airplane Car Boat Robot Controls 4.8V-6V

Description

The FS90R is an analog micro servo that is capable of continuous rotation clockwise or anti-clockwise, as opposed to moving to a set position. The servo can be controlled using any servo code, hardware or library and to control with an Arduino, just connect the orange control wire to pin 9 or 10 and use the Servo library included with the Arduino IDE. Good for beginners who want to make stuff move without having to use a motor controller, especially since it will fit in small places. They may require some simple calibration, simply tell the servo to 'stop' and then gently adjust the potentiometer in the recessed hole with a small screwdriver until the servo stops moving. Review: How to use with Arduino Servo Library - Continuous operation servos like these are different from regular servos but still work well with the Arduino Servo library. The position is not accessible with 360 degree servos. Instead you use the Servo library to set the speed and direction of the motor. Because these are geared motors, you get more torque than you would with a regular DC motor. The 5 servos I received responded perfectly to the Arduino Servo library as described here: servo.write(0); // fast CW servo.write(180); // fast CCW servo.write(90); // stop // 0 to 90 (fast to slow) CW, front view) // 90 to 180 (slow to fast) CCW, front view) // 90 = stop If you look at the pulse widths generated for each of these settings and the operation of 360 degree servos, this is all as it should be. You should never have to cut the power to stop the servo. Review: Worked as they should - Worked as they were supposed to.
