FEETECH FS90-FB Micro Servo with Position Feedback

/*
Here's an example code to control a FEETECH FS90-FB Micro Servo with Position Feedback using an Arduino. This code demonstrates how to move the servo to different positions and read the position feedback from the servo's built-in potentiometer.

To use this code, connect the FEETECH FS90-FB Micro Servo's signal wire to the specified pin on your Arduino board (in this case, pin 9) and the feedback wire to the analog pin A0. Upload the code using the Arduino IDE and open the Serial Monitor to see the servo's position feedback.

Remember to power the servo using an appropriate power supply, typically 4.8V to 6V, with the servo's red wire connected to the positive voltage supply and the black or brown wire connected to the ground. Connect the ground from the servo's power supply to the ground of the Arduino to ensure a common ground reference.

This example code moves the servo to 0, 90, and 180 degrees while reading and displaying the position feedback. You can modify this code to suit the specific requirements of your project or application.
