Hello everyone,
Anyone has knowledge on how to fix the position of cont. rot. servo motor
I have to use this motor because I also have to use servo shield PCA9685 for the ability of using big number of motors with only one arduino.
My prototype works like a vending machine the servo must rotates 360 degree and then stops at certain point exactly every time it rotates when recieving a signal from the user. But by using normal programming library of Adafruit, there is a difference in the position each time it rotates. I really need something to get it to the same point again every time, I heard about encoder is it possible and how can I use it? or is there any easier solution? please share me your knowledge in details because I need to do it for my graduation project. Thank you.
Use a normal servo for your project, not a continuous rotation servo.
Sail winch servos can rotate 360 degrees or more.

I don't think an encoder is necessary - a simple optical interrupter could maybe do the job
Maybe by adding a microswitch to the spiral of the vending machine. This way you will know when it rotate 1 turn.
