Use android app to control multiple servo motor connected to your arduino, I used arduino uno, it has only 6 PWM pins , that's the reason I stopped with 6 slider in the android app, if you want to control more than 6, you can use arduino mega or any other board which offers more pins to control more servos. the app was created using MIT app inventor which can be done in less than 20 minutes. This project can be used to control applications where we need to control multiple servos.
How to make Mit app inventor block for controlling multiple servo motors:
