We will control 5 servo motor using with 5 pcs flex sensor. Also we will controlled robotic hand using with nRF24L01. This video shows the low-cost “robotic hand” construction.

Making a servo tester using an Attiny85 micro chip, Attiny45 also works for this project. This diy servo tester is as good as ...

They represent a significant leap forward in terms of functionality and ease of use, offering a solution to many of the issues that have traditionally plagued servo motors and controllers.
